Title
MISP Dashboard Template ACL Bypass Due to VARCHAR-to-Integer Type Coercion in Permission Flag Comparison
Summary
Affected versions of MISP incorrectly filter dashboard templates that are restricted to a specific permission flag.
DashboardsController::listTemplates() allowed a template when either:
- its restrict_to_permission_flag matched one of the current user’s permission flags, or
- restrict_to_permission_flag equaled integer 0
However, restrict_to_permission_flag is a varchar. MySQL therefore performed numeric coercion when comparing the column against integer 0. Strings such as perm_site_admin convert numerically to zero, making expressions such as perm_site_admin = 0 evaluate true and causing the “unrestricted” branch to match permission-restricted templates as well.

fix: [acl] Compare the dashboard template permission flag as | ac03cd1103d5… |
Fix summary
The fix corrects the type mismatch in the permission flag comparison by replacing the integer literal 0 with the explicit string values '' and '0', which are the actual database values representing an unrestricted dashboard template. This ensures MySQL performs a proper string-to-string comparison, so only rows genuinely marked as unrestricted are returned, restoring the intended per-permission-level access control on dashboard templates.
Patch summary
In app/Controller/DashboardsController.php, the listTemplates() method's query condition was changed from ['Dashboard.restrict_to_permission_flag' => 0] to ['Dashboard.restrict_to_permission_flag' => ['', '0']]. A multi-line comment was added explaining that restrict_to_permission_flag is a VARCHAR column and that comparing it to integer 0 causes MySQL to coerce the column, making the clause a no-op. The two values that actually represent unrestricted access are the empty string (column default) and the string '0' (posted by the save form).
CVSS rationale
The vulnerability is exploitable over the network (AV:N) via the MISP web interface with low attack complexity (AC:L) and no attack target manipulation (AT:N). It requires a low-privilege authenticated user (PR:L) and no user interaction (UI:N). The impact is limited to confidentiality (VC:L) as restricted dashboard template definitions are disclosed to unauthorized users; there is no integrity or availability impact (VI:N, VA:N) and no secondary effects (SC:N, SI:N, SA:N). The severity is moderate because the disclosed data is dashboard template metadata rather than raw threat intelligence, but it still represents a breach of the intended access control boundary.
Weakness rationale
- CWE-863 The permission-based filter on dashboard templates was effectively bypassed because the type-coerced comparison matched all rows, allowing any authenticated user to access templates restricted to higher-privilege roles. The authorization check was present in code but did not function correctly.
- CWE-697 The root cause is a comparison between a VARCHAR column and an integer literal. MySQL's implicit type coercion caused the comparison to evaluate to TRUE for all non-numeric string values, making the intended filter a no-op. This is a classic incorrect comparison due to type mismatch.
Assumptions to verify
- The affected version range is inferred from the tag_version_boundary (v2.5.46 with 200 commits after fix); no explicit affected or fixed version is stated in the patch metadata.
- The vulnerability requires an authenticated MISP user with any role; the exact minimum privilege level needed to access the listTemplates endpoint is not specified in the patch.
- The impact is assessed as Low confidentiality because the disclosed data is dashboard template definitions (layout, widget configuration) rather than raw threat intelligence or user credentials.
- The MySQL type-coercion behavior described in the commit message and code comments is assumed to be accurate for the MySQL versions supported by MISP.

In affected versions of Octopus Server, users with certain scoped permission sets could execute arbitrary scripts on a worker (including the Octopus Server built-in worker). Incorrect permission validation during script execution would allow the script to execute without the user possessing the required authorisation.

Title
Warpgate: API tokens bypass the user's allowed_ip_ranges restriction
Summary
Warpgate is an open source SSH, HTTPS and MySQL bastion host for Linux. From 0.23.0 until 0.27.3, HTTP API token authentication resolves ConfigProvider::validate_api_token into RequestAuthorization::UserToken without enforcing the owning user's allowed_ip_ranges against the trusted client address in warpgate-protocol-http/src/common.rs. An attacker holding a leaked, phished, or exfiltrated X-Warpgate-Token can therefore use it from a prohibited network location. Deployments without allowed_ip_ranges are unaffected, and HTTP target proxying plus SSH, MySQL, PostgreSQL, RDP, VNC, and Kubernetes paths do not accept this vulnerable HTTP token flow. This issue is fixed in version 0.27.3.

Title
Casdoor through 4.4.0 Private Key Exposure via Certificate Endpoints
Summary
Casdoor through 4.4.0 fails to properly mask the instance-wide built-in certificate private key in /api/get-certs and /api/get-cert endpoints, allowing organization administrators to retrieve it. Attackers can use the exposed private key to forge JWT tokens for any user in any organization, including global administrators.

Title
EspoCRM before 10.0.4 Field-level Security Bypass via Attendees
Summary
EspoCRM before 10.0.4 contains a field-level security bypass vulnerability in the meeting and call attendees endpoints that allows authenticated users to read restricted email addresses. Attackers can recover hidden attendee emails by exploiting incorrect ACL scope validation that checks parent event permissions instead of attendee entity permissions.

Mitigation
Architecture and Design
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration
Installation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
