    Title
    [ADVISORY] Multiple Integer Overflows in U-Boot Filesystem Parsing (CVE-2025-70290 through CVE-2025-70293)
    Summary
    -----BEGIN SECURITY ADVISORY----- Title: Multiple Integer Overflows in U-Boot Filesystem Handling Author: Timo Preißl <t.preissl () proton me> Date: 2026-02-11 CVEs: CVE-2025-70290, CVE-2025-70291, CVE-2025-70292, CVE-2025-70293 Affected: Denx U-Boot <= v2026.01-rc4 Fixed in: v2026.04-rc1 (commit adccdb2) == Overview == Multiple integer overflow vulnerabilities were discovered in the U-Boot bootloader's filesystem handling code and command-line interface. These flaws can lead to heap memory under-allocation followed by heap-based buffer overflows, potentially allowing Arbitrary Code Execution (ACE) in the pre-boot environment. == Vulnerability Details == --- CVE-2025-70290: ZFS Metadata Integer Overflow --- Component: fs/zfs/zfs.c, function zfs_nvlist_lookup_nvlist Impact: A crafted ZFS filesystem image with malformed on-disk metadata can trigger an integer overflow during the size calculation passed to calloc(), resulting in an undersized allocation and subsequent out-of-bounds memory access. Fix: Validation of allocation size using __builtin_add_overflow. --- CVE-2025-70291: Heap Buffer Overflow in do_mv Command --- Component: fs/fs.c, function do_mv Impact: Missing length checks in the directory move command allow an integer overflow during string length addition. An attacker with U-Boot shell access can trigger an under-allocation, resulting in a heap buffer overflow via strcpy(). Fix: Safe addition of string lengths using compiler intrinsics. --- CVE-2025-70292: SquashFS Integer Overflow --- Component: fs/squashfs/sqfs.c, function sqfs_concat_tokens Impact: Manipulated token lists trigger an overflow in sqfs_get_tokens_length(), causing heap under-allocation subsequently overflown by strcpy(). Fix: Validation of total token length before allocation. --- CVE-2025-70293: EXT4 Block Group Descriptor Table Integer Overflow --- Component: fs/ext4/ext4_write.c, function ext4fs_get_bgdtable Impact: An integer overflow in the block group descriptor table size calculation results in an undersized buffer being passed to memcpy(), causing memory corruption. Fix: Guarded multiplication of block group count and descriptor size. == Patch == All issues are fixed in the U-Boot master branch.

    [SECURITY ADVISORY] CVE-2026-34473 - Unauthenticated DoS in 17+ ZTE Router Models (140K+ Devices)
    Summary
    -----BEGIN SECURITY ADVISORY----- Advisory ID: MONX-2026-001 CVE ID: CVE-2026-34473 Title: Unauthenticated Denial of Service via Oversized POST Body in ZTE Router CGILua Parser Affected: 17+ ZTE ZXHN router models (~140,000 publicly exposed devices) CVSS Score: 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) Date: 2026-05-20 Author: Mina Nageh Salalma (Monx Research) Contact: minanageh379 () gmail com Public URL: https://github.com/minanagehsalalma/cve-2026-34473-unauthenticated-dos-zte-routers MITRE: https://www.cve.org/CVERecord?id=CVE-2026-34473 AFFECTED PRODUCTS ----------------- 17+ ZTE ZXHN router models sharing the CGILua firmware stack. Estimated 140,000+ devices publicly reachable on the Internet at time of research. VULNERABILITY DESCRIPTION -------------------------- The CGILua post.lua parser used in ZTE ZXHN routers does not enforce an upper bound on the body size of application/x-www-form-urlencoded POST requests. An unauthenticated attacker can crash or freeze the router's web management service by sending a single HTTP POST request with an oversized body to any CGI endpoint. No authentication, session cookie, or prior access is required. ROOT CAUSE ---------- Firmware analysis of extracted squashfs images confirms that post.lua reads the entire POST body into memory before parsing. There is no Content-Length check or body-size limiter before the allocation occurs. Oversized payloads cause the LuCI/CGILua process to exhaust memory or fault, taking down the web management interface until the device is power-cycled. PROOF OF CONCEPT ---------------- import requests url = "http://TARGET_IP/cgi-bin/luci"; payload = "a=" + "A" * (256 * 1024) # 256 KB headers = {"Content-Type": "application/x-www-form-urlencoded"} try: r = requests.post(url, data=payload, headers=headers, timeout=15) print(f"HTTP {r.status_code}") except requests.exceptions.Timeout: print("Timeout - DoS successful") except requests.exceptions.ConnectionError: print("Connection dropped - DoS successful") IMPACT ------ An unauthenticated attacker on the LAN or WAN (if management interface is publicly exposed, as is the case for ~140,000 devices) can permanently disable remote management access, forcing a physical reboot to restore access. ISP-deployed devices with no physical access for end users are especially vulnerable. TIMELINE -------- 2024-05: Local validation on hardware. Firmware extraction and root-cause confirmed. 2024-05: Report sent to ZTE PSIRT. 2025-01: Escalated to MITRE after ZTE failed to respond. 2026-03: MITRE assigned CVE-2026-34473. 2026-05-20: Full public disclosure. VENDOR RESPONSE --------------- ZTE PSIRT did not respond to the initial report. MITRE assigned the CVE directly. No patch has been issued.

    [SECURITY ADVISORY] CVE-2021-21735 - ZTE ZXHN H168N V3.5 Unauthenticated Admin Credential Leak
    Summary
    -----BEGIN SECURITY ADVISORY----- Advisory ID: MONX-2021-001 CVE ID: CVE-2021-21735 Title: ZTE ZXHN H168N V3.5 - Unauthenticated Wizard Credential Disclosure to Full Admin Compromise Affected: ZTE ZXHN H168N V3.5 Date: 2026-05-20 Author: Mina Nageh Salalma (Monx Research) Contact: minanageh379 () gmail com Public URL: https://github.com/minanagehsalalma/cve-2021-21735-zte-zxhn-h168n-admin-compromise MITRE: https://www.cve.org/CVERecord?id=CVE-2021-21735 VULNERABILITY DESCRIPTION -------------------------- The ZTE ZXHN H168N V3.5 firmware exposes quick-setup wizard endpoints that return PPPoE credentials (ADUsername, VDUsername) and the WLAN KeyPassphrase via the GetPassword action without requiring authentication. The firmware routing allowlists these endpoints through a QuickSetupEnable branch. In ISP-deployed configurations where the Wi-Fi password is reused as the default admin password, this credential disclosure is a full admin compromise chain requiring a single unauthenticated HTTP request. A bulk PoC script (zte_zxhn_h168n_bulk_poc.py) is included in the repository for verifying scale of exposure.

The leaked Wi-Fi password is also the default administrator password after uppercasing, resulting in full authentication bypass. ROOT CAUSE ---------- router_logic_impl.lua accepts attacker-controlled _type and _tag parameters for empty-path requests. urlpath_2type_modifier.lua only activates the QuickSetupEnable gate when _type is absent. Supplying _type explicitly causes the wizard handlers (getPassword, wlan_get, ppp_get) to execute for unauthenticated requests, returning WLAN PSKs, SSIDs, and PPPoE credentials.

    Multiple vulnerabilities in Sparx Pro Cloud Server and Enterprise Architect
    Summary
    ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Multiple vulnerabilities in Sparx Pro Cloud Server and Enterprise Architect ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ General information ═══════════════════ Multiple vulnerabilities in Sparx Pro Cloud Server (PCS) versions <= 6.1 and Sparx Enterprise Architect versions <=17.1 allow a remote unauthenticated attacker to execute arbitrary sql queries (both read and write) within any configured database. In case where PCS is installed with WebEA the vulnerabilities allow further for remote unauthenticated code execution (RCE) within the web server context. CVSSv4 chained score: *10.0 Critical* (AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H) Fix ═══ Currently vendor *did not resolve* any of the CVEs. The PCS authentication bypass and race condition seem to be easy to implement and I hope vendor will release patches soon. As a workaround it is best to isolate the PCS instances from internet and untrusted networks. Create frequent backups and review access logs if possible. You could also setup a proxy to limit the PCS authentication bypass (dropping requests with no or wrong model query parameter. [Vulnerabilitiy #1] Sparx Pro Cloud Server SQL Command Execution ════════════════════════════════════════════════════════════════ CVE ─── CVE-2026-42096 - Broken Access Control in Sparx Pro Cloud Server Affected versions ───────────────── Sparx Pro Cloud Server versions <= 6.1 build 167 CVSSv4 ────── 9.4 Critical (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H) Impact ────── PCS works as a remote model for a thick client, running on user's computers, called Enterprise Architect (EA). EA connects to PCS and works with the exposed database by directly running SQL queries. Besides user authentication (which is also vulnerable - see vulnerability #2 below) there is no additional access control. Any low privileged user can actually run any sql queries permitted by the configured external database user. Usually the user configured is at least having full access to the model database - thus any low privileged user can actually destroy the whole model, retrieve and change other user's password hashes and more. The problem seems to be with legacy thick client EA architecture which simply works on a database to manage all the model details. Details ─────── The client (EA) is connecting to the PCS HTTP server. The server might require authentication *if it is properly configured* - an admin can check "Enable Security" in EA but still not select "Require a secure and authenticated connection" in PCS configuration what results in *NO SERVER SIDE authentication at all*. Assuming the server side authentication is required the PCS verifies the authentication according to configuration - e.g. login/password, Active Directory or OpenID. Then the EA client sends request to perform SQL queries on the database in an ecrypted form but the whole encryption scheme is built into the client EA binary (actually downloadable from the vendor webside without any authentication - as trial version). The encryption is symmetric using a key contained within the binary itself thus simply this is not any security measure (security by obscurity). An attacker can obtain the key and then *create and send custom SQL queries to be performed by the database*. PoC ─── Exploit: https://github.com/br0xpl/sparx_hack/blob/main/eacrypt.py is a python script which exploits the SQL vulnerability by encrypting any SQL command and sending it to the server. For security, the real key is removed from the exploit code. This script receives all users and their hashes from PCS: ┌──── │ python3 eacrypt.py http://${PCS_HOSTNAME} model "select * from t_secuser, t_xref where t_xref.Type='User Setting' and t_xref.Name ='SHA-256' and t_xref.Client=t_secuser.UserID" └──── Solution ──────── It will be hard to introduce proper authorization for all types of SQL queries - this would require to rewrite the logic to use some higher abstraction API which can be properly authorized. Until a proper authorized API will be provided a quick solution could be at least to verify the SQL queries executed and block the most dangerous like asking about other users' passwords and so on. Maybe a query whitelist with limiting the view of some critical assets like hashes. For sure it should be transparently stated in the PCS and EA documentation web page. Some integrators and admins are aware of this risk (there are some topics on the forum mentioning that the model security is not in fact security) but this *should be well described in both product documentations* as a limitation and risk which needs to be understood by clients and taken into consideration at an early stage while designing a production system. Otherwise it poses a high risk for any company using those products. [Vulnerability #2] Sparx Pro Cloud Server Authentication Bypass ═══════════════════════════════════════════════════════════════ CVE ─── CVE-2026-42097 - Authentication Bypass in Sparx Pro Cloud Server Affected versions ───────────────── Sparx Pro Cloud Server versions <= 6.1 build 167 CVSSv4 ────── 9.2 Critical (CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) Impact ────── An attacker can *omit PCS authentication* and e.g. combined with the previous vulnerability be able to remotely execute arbitrary SQL commands (read and write) *without authentication*. Details ─────── It seems that PCS requires authentication based on requested URL. EA clients sending the encrypted SQL query to PCS are using an url which looks as follows: ┌──── │ https://${PCS_SERVER_HOSTNAME}/SparxCloudLink.sseap?model=${MODEL_NAME} └──── PCS seems to look at the URL and decides how to authenticate the request. Unfortunately the SQL command query sends a POST request with a binary blob where the model name is defined one more time and this is the value that is further used by PCS to execute the query. Thus an attacker can simply omit the model query parameter and send the model name only in the binary blob in both TLS and non-TLS ports and the query will be executed even thought there was no authentication. PoC ─── To quickly verify compare the authenticated response for a request: ┌──── │ curl 'https://${PCS_HOSTNAME}/SparxCloudLink.sseap?model=${MODEL_NAME}' -X POST -vvv --data 'whatever' -k └──── which responds 401 Access Denied to response of a request without the query param: ┌──── │ curl 'https://${PCS_HOSTNAME}/SparxCloudLink.sseap' -X POST -vvv --data 'whatever' -k └──── which responds 500 Internal Server Error. To proof this properly use the python code which exploits the #1 SQL vulnerability and uses the URL without model query parameter to omit the authentication. Solution ──────── Make a single parameter pointing the model (either in the blob or in query param) and hook authentication and query logic on the same parameter. [Vulnerability #3] Sparx Enterprise Architect Authorization Bypass ══════════════════════════════════════════════════════════════════ CVE ─── CVE-2026-42098 - Authorization Bypass in Sparx Enterprise Architect Affected versions ───────────────── Sparx Enterprise Architect versions <= 17.1 CVSSv4 ────── 7.7 High (CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N) Impact ────── Sparx Enterprise Architect software has a security feature which can be enabled. When enabled the users can be limited to perform only some actions by roles but this is not a real security measure as it can be easily bypassed. *Any authenticated user can actually perform any action on the model* including deletion, stealing of other users' passwords and many others. This *includes configurations with Pro Cloud Server* where vendor advertises that PCS brings high level of security for the model: Robust security features are designed to protect sensitive model information, *including role-based access control*, encryption, authentication mechanisms and audit trails. source: <https://www.sparxsystems.eu/pro-cloud-server/> Details ─────── This vulnerability, most probably, is a result of the legacy thick client architecture described in the vulnerability #1. The EA documentation states briefly that the security is not a real security: The Security system in Enterprise Architect is designed to facilitate collaboration, *not as a barrier to incursion*. source: <https://sparxsystems.com/enterprise_architect_user_guide/17.1/guide_books/tools_ba_security.html> but right below it suggests that model assets should be secured: The information contained in the Repository is a valuable organizational asset that needs to be maintained and secured as such. The asset must be protected from both *intentional* and inadvertent compromises of content. The Security system allows update functions to be restricted to a set of users or groups with the appropriate defined permission. Packages, elements and diagrams can be locked by users, preventing others from updating them. source: <https://sparxsystems.com/enterprise_architect_user_guide/17.1/guide_books/tools_ba_security.html> Unfortunately the current design is not protecting against intentional compromises of content. An attacker can modify the EA client behavior (e.g. using a debugger) to login in as any other user or administrator - then it is possible to do every possible change to the repository. PoC ─── To show how it works it is enough to patch the binary to change the logic and accept all incorrect passwords and reject correct ones. For the file version 17.1.0.1714 of EA.exe (md5sum: 69dfe7b98d1fc156d15d8aeff726cfce) the following would patch the logic: ┌──── │ printf '\x84' | dd of=EA.exe bs=1 seek=$((0x34657B2)) conv=notrunc └──── Then run the patched exe and try to login to local model with different password. It also works obviously for cloud models which do not require server HTTP authentication or when using the "Login as different user option". Solution ──────── The way security works for EA should be properly and transparently presented in the EA documentation and installation notes. The sentence quoted above is not enough and can be easily misinterpreted by many users leading to vulnerabilities. Also it should be explained that even when using PCS after authentication there is no authorization until visibility levels are enabled which are working per whole database manager not user - so in fact there is no user based RBAC but rather database manager RBAC what is much more coarse grained then per user roles access control. In terms of combination of EA and PCS it is possible to secure the design by e.g. following the recommendations proposed in vulnerability #1. [Vulnerability #4] Sparx Pro Cloud Server WebEA Remote Code Execution ═════════════════════════════════════════════════════════════════════ CVE ─── CVE-2026-42099 - Race Condition in Sparx Pro Cloud Server Affected versions ───────────────── Sparx Pro Cloud Server versions <= 6.1 build 167 CVSSv4 ────── 9.0 Critical (CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H) Impact ────── PCS configured with WebEA PHP application allows for remote command execution using the /data_api/dl_internal_artifact.php endpoint. This URL is used by WebEA to download content of a internal artifact. A remote attacker having access to the PCS repository is able to inject a malicious php file into the

Unfortunately the SQL command query sends a POST request with\n  a binary blob where the model name is defined one more time and this\n  is the value that is further used by PCS to execute the query.\n\n  Thus an attacker can simply omit the model query parameter and send\n  the model name only in the binary blob in both TLS and non-TLS ports\n  and the query will be executed even thought there was no\n  authentication.\n\n\nPoC\n\u2500\u2500\u2500\n\n  To quickly verify compare the authenticated response for a request:\n  \u250c\u2500\u2500\u2500\u2500\n  \u2502 curl \u0027https://${PCS_HOSTNAME}/SparxCloudLink.sseap?model=${MODEL_NAME}\u0026apos; -X POST  -vvv --data \u0027whatever\u0027 -k\n  \u2514\u2500\u2500\u2500\u2500\n\n  which responds 401 Access Denied to response of a request without the\n  query param:\n\n  \u250c\u2500\u2500\u2500\u2500\n  \u2502 curl \u0027https://${PCS_HOSTNAME}/SparxCloudLink.sseap\u0026apos; -X POST  -vvv --data \u0027whatever\u0027 -k\n  \u2514\u2500\u2500\u2500\u2500\n\n  which responds 500 Internal Server Error.\n\n  To proof this properly use the python code which exploits the #1\n  SQL vulnerability and uses the URL without model query parameter to\n  omit the authentication.\n\n\nSolution\n\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n\n  Make a single parameter pointing the model (either in the blob or in\n  query param) and hook authentication and query logic on the same\n  parameter.\n\n\n[Vulnerability #3] Sparx Enterprise Architect Authorization Bypass\n\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\n\nCVE\n\u2500\u2500\u2500\n\n  CVE-2026-42098 - Authorization Bypass in Sparx Enterprise Architect\n\n\nAffected versions\n\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n\n  Sparx Enterprise Architect versions \u003c= 17.1\n\n\nCVSSv4\n\u2500\u2500\u2500\u2500\u2500\u2500\n\n  7.7 High\n  (CVSS:4.0/AV:N/AC:H/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N)\n\n\nImpact\n\u2500\u2500\u2500\u2500\u2500\u2500\n\n  Sparx Enterprise Architect software has a security feature which can\n  be enabled.

This *includes configurations with Pro Cloud Server* where\n  vendor advertises that PCS brings high level of security for the\n  model:\n\n        Robust security features are designed to protect sensitive\n        model information, *including role-based access control*,\n        encryption, authentication mechanisms and audit trails.\n\n        source: \u003chttps://www.sparxsystems.eu/pro-cloud-server/\u003e\n\n\nDetails\n\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n\n  This vulnerability, most probably, is a result of the legacy thick\n  client architecture described in the vulnerability #1.\n\n  The EA documentation states briefly that the security is not a real\n  security:\n\n        The Security system in Enterprise Architect is designed to\n        facilitate collaboration, *not as a barrier to incursion*.\n\n        source:\n        \u003chttps://sparxsystems.com/enterprise_architect_user_guide/17.1/guide_books/tools_ba_security.html\u003e\n\n  but right below it suggests that model assets should be secured:\n\n        The information contained in the Repository is a valuable\n        organizational asset that needs to be maintained and\n        secured as such. The asset must be protected from both\n        *intentional* and inadvertent compromises of content. The\n        Security system allows update functions to be restricted\n        to a set of users or groups with the appropriate defined\n        permission. Packages, elements and diagrams can be locked\n        by users, preventing others from updating them.\n\n        source:\n        \u003chttps://sparxsystems.com/enterprise_architect_user_guide/17.1/guide_books/tools_ba_security.html\u003e\n\n  Unfortunately the current design is not protecting against intentional\n  compromises of content. An attacker can modify the EA client behavior\n  (e.g. using a debugger) to login in as any other user or administrator\n  - then it is possible to do every possible change to the repository.\n\n\nPoC\n\u2500\u2500\u2500\n\n  To show how it works it is enough to patch the binary to change the\n  logic and accept all incorrect passwords and reject correct ones. For\n  the file version 17.1.0.1714 of EA.exe (md5sum:\n  69dfe7b98d1fc156d15d8aeff726cfce) the following would patch the logic:\n\n  \u250c\u2500\u2500\u2500\u2500\n  \u2502 printf \u0027\\x84\u0027 | dd of=EA.exe bs=1 seek=$((0x34657B2)) conv=notrunc\n  \u2514\u2500\u2500\u2500\u2500\n\n  Then run the patched exe and try to login to local model with\n  different password. It also works obviously for cloud models which do\n  not require server HTTP authentication or when using the \"Login as\n  different user option\".\n\n\nSolution\n\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n\n  The way security works for EA should be properly and transparently\n  presented in the EA documentation and installation notes. The sentence\n  quoted above is not enough and can be easily misinterpreted by many\n  users leading to vulnerabilities.\n\n  Also it should be explained that even when using PCS after\n  authentication there is no authorization until visibility levels are\n  enabled which are working per whole database manager not user - so in\n  fact there is no user based RBAC but rather database manager RBAC what\n  is much more coarse grained then per user roles access control.\n\n  In terms of combination of EA and PCS it is possible to secure the\n  design by e.g. following the recommendations proposed in vulnerability\n  #1.\n\n\n[Vulnerability #4] Sparx Pro Cloud Server WebEA Remote Code Execution\n\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\u2550\n\nCVE\n\u2500\u2500\u2500\n\n  CVE-2026-42099 - Race Condition in Sparx Pro Cloud Server\n\n\nAffected versions\n\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\u2500\n\n  Sparx Pro Cloud Server versions \u003c= 6.1 build 167\n\n\nCVSSv4\n\u2500\u2500\u2500\u2500\u2500\u2500\n\n  9.0 Critical\n  (CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H)\n\n\nImpact\n\u2500\u2500\u2500\u2500\u2500\u2500\n\n  PCS configured with WebEA PHP application allows for remote command\n  execution using the /data_api/dl_internal_artifact.php endpoint.

    Re: Multiple Security Misconfigurations and Customer Enumeration Exposure in Convercent Whistleblowing Platform (EQS Group)
    Summary
    Hello Yuffie, Upon further investigation, the VulnCheck CNA determined that these vulnerabilities were not suitable for CVE assignment. The vulnerabilities exist within a SaaS product and are mitigated at the CSP-level which in this case, would be the vendor, EQS Group. Rather than contribute unactionable CVE records, the VulnCheck CNA used its discretionary prowess to move forward with rejecting these records. This policy aligns with a 2022 blog from MITRE <https://www.cve.org/Media/News/item/blog/2022/09/13/Dispelling-the-Myth-CVE-ID>. It should be noted that the vendor informed us that they have published advisories for the respective vulnerabilities in their "Trust Center" customer portal. These actions should not be a deterrent for you to pursue CVE assignment through MITRE or another research CNA.

    Dear Art, Thank you for sharing your detailed evaluation and for pointing out the relevant sections of the CNA Rules. Your argument is well reasoned, particularly with respect to the current guidance on SaaS and exclusively hosted services. I have forwarded your evaluation to the CNA for further consideration. It will also be important to understand the vendor’s perspective in light of the points you raised, especially regarding the applicability of the “exclusively-hosted-service” tag and the removal of prior restrictions. We look forward to receive transparent feedback from the CNA and/or the vendor. To date, the vendor has remained silent with regard to informing their users about the reported issues. As far as we can determine, no public advisory or user-facing communication has been issued via their vulnerability reporting channel () or elsewhere.

    Re: Multiple Security Misconfigurations and Customer Enumeration Exposure in Convercent Whistleblowing Platform (EQS Group)
    Summary
    Hello everyone, Kindly let me introduce myself. This is the first – and potentially, last – message on this mailing list. I am Marco, the CISO of EQS Group. Kindly allow me to address some of the statements expressed publicly here. About the Convercent application Convercent was acquired by OneTrust in 2021, and in turn, EQS has acquired it from OneTrust at the end of 2024. Before being acquired by EQS, the Convercent application has not received much love in the latest years, and EQS has since then proceeded to migrate its customers to the EQS Compliance COCKPIT, which is a modern, supported, and secure SaaS. The Convercent application is sunset and will be finally switched off by mid of 2026. Currently, Convercent is supported by EQS on a best-effort basis; despite that, EQS Group has committed to fix all critical vulnerabilities until the last customer is fully migrated. We want our customers to migrate to our best service because it is better – not rush them in our new product because what we inherited from an acquisition is insecure. The vulnerabilities The two issues disclosed are either minor in nature or do not constitute vulnerabilities. One was a lack of certain HTTP headers (some of the reported ones where wrong, but regardless, still hardly something CVE-worthy), and the second was about an “exposed” API; however, it is public by design as this is how the application works: it is a page where customers – who have explicitly agreed and signed off to be present – are added to a drop-down list, fed from this public API. The web page exposes the list of customers by design. While we may reasonably question whether this page reflects current secure-by-design standards, this brings zero added risk to any of the EQS customers and Convercent users. I strongly disagree with the ideas that those “vulnerabilities” could become CVEs – regardless of the status of the SaaS security and how CVEs are handled. Therefore, we proceeded to ask for their removal from the CVSS database, so not to alarm our customers with false positives. The responsible CNA agreed immediately to remove them (thank you very much, VulnCheck!). Communication with our customers EQS Group communicates with its customers through established and appropriate channels – notably, our Trust Center – and not via anonymous mailing lists. Customers have received and will continue to receive all the notifications they have contractually required to obtain, and where relevant, additional context beyond those obligations. Customers have received a briefing about the activity happening on this mailing list via our Trust Center. The status of SaaS Security As EQS Group is a CNA candidate, we participate and closely follow discussions between MITRE, CISA, and the German BSI, about vulnerability reporting for SaaS. While we have not heard any news on this front since the last two years, EQS Group remains committed to aligning with applicable best practices as they evolve. We believe that meaningful progress in SaaS security is best achieved through structured, collaborative forums with clear governance, rather than responding to ad-hoc reports of unvetted findings. EQS Group already participates to proper, professional working groups on SaaS security, for instance through the Cloud Security Alliance. If other working groups will emerge through any of the official organisms already mentioned, we will certainly participate. In general, as a principle, CVEs have been created many years ago, at a time where “the Cloud” did not exist in its current form. They were conceived so that users who procured a software from a development company and installed it on their system, could be notified when the software they have installed, manifested a security issue. In that way, they could procure the patch and fix it before a misuse could happen. Now, except for very particular and edge cases, this is largely inapplicable to SaaS, where there is very little users can do and solely rely on the Cloud Service Provider to fix any vulnerability. There is almost never any real ground for a SaaS provider to notify a customer – unless of course a breach has been detected, but in that case we are way beyond a CVE and we are on a different territory. For a SaaS, even knowing that the application had a bug, does not help the user in any way. This is why typically CVEs as a concept are not the proper tool to address SaaS vulnerabilities, and in general, rushing to disclose them only damages the users; a disclosure does not help them in any way. Response to the “Responsible" Disclosure About the “responsible" disclosure: EQS Group receives a significant volume of “vulnerability notifications” like that one. Almost all of them are low or irrelevant issues from anonymous users looking to make a buck; they are typically about a missing HTTP headers or lack of optional DNS records. Given the scale of our environment, it can happen that some record is not updated, but this has little relevance to the security of our platforms. We also cannot always reply to all those messages, and most of them seem AI or automatically generated. The notification from “Yuffie Kisaragi” was sent to us on the 4th of December and went to Junk due to the low reputation of the email used. The author then rushed to obtain two CVE IDs less than two weeks later and subsequently lost no time posting them on this list. EQS Group is certainly not perfect, but if these would have been real vulnerabilities, I argue that this would have not qualified as a “responsible” disclosure by any reasonable standard. Further communications EQS Group’s vulnerability handling policy is listed here<https://www.eqs.com/report-a-vulnerability/#handle> – https://www.eqs.com/report-a-vulnerability/ – and we strongly suggest anyone to read it before they issue a report. In this regard, we would like to point out the followings: 1. For several reasons – legal, commercial, policy, and ethical – EQS Group is unable to respond to requests for payment of bounties outside of an official bug bounty program. 2. EQS Group does nor remunerate bugs that were already discovered internally and were already in resolution. 3. EQS Group strongly discourages non-approved, un-vetted testing on EQS Group’s infrastructure. They can and will be perceived as hostile activity. Testing is encouraged only within officially approved bug bounty programs, in respect to the established rules of engagement. 4. Kindly avoid pointless reports on MTA-STS records, DMARC, quantum ciphers, and other junk like that. It makes our life easier. Thank you for your attention.

    Title
    Multiple Security Misconfigurations and Customer Enumeration Exposure in Convercent Whistleblowing Platform (EQS Group)
    Summary
    UPDATE: Following the publication of these vulnerabilities and the subsequent CVE assignments, the CVE identifiers have now been revoked. The vendor (EQS Group) contacted the CVE Program (via a CNA) and disputed the records, stating that the affected product is an exclusively hosted SaaS platform with no customer-managed deployment or versioning. Based on this argument, the CVE Program concluded that CVE assignment is “not a suitable solution for vulnerability identification” in this case, as customers do not take direct action to apply fixes. In other words, because the service is centrally hosted and patched at the provider’s discretion, the vulnerabilities are no longer considered eligible for CVE tracking, despite being real, independently discovered, responsibly disclosed, and acknowledged by the vendor. The vendor has stated that fixes are being implemented and that private customer notifications will be issued internally. While remediation is of course welcome, this outcome highlights a broader issue: vulnerabilities in SaaS platforms can effectively disappear from public vulnerability tracking, simply because the deployment model removes user agency, a model that arguably incentivizes security through obscurity, rather than transparency. The technical findings remain valid. This update is shared purely for accuracy and record-keeping.

    Re: Multiple Security Misconfigurations and Customer Enumeration Exposure in Convercent Whistleblowing Platform (EQS Group)
    Summary
    Hi, the vulnerabilities are no longer considered eligible for CVE tracking, despite being real, independently discovered, responsibly disclosed, and acknowledged by the vendor. CVE IDs *can* be assigned for SaaS or similarly "cloud only" software. For a period of time, there was a restriction that only the provider could make or request such an assignment. But the current CVE rules remove this restriction: 4.2.3 CNAs MUST NOT consider the type of technology (e.g., cloud, on-premises, artificial intelligence, machine learning) as the sole basis for determining assignment. It would have been acceptable (even preferred) to leave CVE-2025-34411 and CVE-2025-34412 published and identify them as affecting an "exclusively-hosted-service:" 5.1.11.1 (A CVE Record) MUST use the “exclusively-hosted-service” tag when all known Products listed in the CVE Record exist only as fully hosted services. If the Vulnerability affects both hosted services and on-premises Products, then this tag MUST NOT be used.
