CVE-2026-4387 (GCVE-0-2026-4387)

Vulnerability from cvelistv5 – Published: 2026-05-29 18:28 – Updated: 2026-06-01 16:26
VLAI
Title
Unencrypted storage of authentication state in StrongDM Desktop Application state.kv file
Summary
StrongDM Desktop Application before 23.74.0 (Desktop Client before 53.77.0) on Microsoft Windows stores authentication state, including a JSON Web Token and asymmetric key material, in cleartext in a per-user state file located at C:\Users\<username>\.sdm\state.kv. The file is protected only by default user-level NTFS permissions. Exploitation requires local read access to the affected user's profile directory and additional deployment and execution conditions on the target host. The condition was reported through coordinated disclosure by Hope Walker (SpecterOps).

CVE-2026-4346 (GCVE-0-2026-4346)

Vulnerability from cvelistv5 – Published: 2026-03-26 21:16 – Updated: 2026-03-27 19:39

Title
Cleartext Storage of Administrative and Wi-Fi Credentials via Accessible Serial Interface in TP Link's TL-WR850N
Summary
The vulnerability affecting TL-WR850N v3 allows cleartext storage of administrative and Wi-Fi credentials in a region of the device’s flash memory while the serial interface remains enabled and protected by weak authentication. An attacker with physical access and the ability to connect to the serial port can recover sensitive information, including the router’s management password and wireless network key. Successful exploitation can lead to full administrative control of the device and unauthorized access to the associated wireless network.

Title
Subject: Advisory Submission: EZ Game Booster - Cleartext Storage of Sensitive Credentials (CWE-312)
Summary
# Exploit Title: EZ Game Booster v1.0.0 - Cleartext Credentials in user.config # Date: 2026-07-16 # Exploit Author: Alireza Chegini # Vendor Homepage: https://ezsystemrepairs.com # Software Link: https://ezsystemrepairs.com (Free version available) # Version: 1.0.0 (v2.0 exists but not tested - paid license required) # Tested on: Windows 10 / Windows 11 # CVE: Pending ============================================================ 1. Description EZ Game Booster v1.0.0 stores user credentials (username, password, email, licenseKey) in plaintext within a .NET user.config file. This is a CWE-312 vulnerability allowing local credential theft. 2. Affected File Path C:\Users\%USERNAME%\AppData\Local\ezgamebooster\ ezgamebooster_Url_fgj2qz5coiw33xftcp3agaqkgxc51bkk\1.0.0.0\user.config 3. Exposed Fields (stored in cleartext) - username - password - email - fullname - licenseKey - machineCode 4. Sample user.config Structure The following is the exact content of the user.config file found on the researcher’s system: <?xml version="1.0" encoding="utf-8"?> <configuration> <userSettings> <ezgamebooster.My.MySettings> <setting name="username" serializeAs="String"> <value>nimaarek</value> </setting> <setting name="password" serializeAs="String"> <value>CanYouSeeMyPassword?!</value> </setting> <setting name="machineCode" serializeAs="String"> <value>N414NBC****BDBMB</value> </setting> <setting name="role" serializeAs="String"> <value>Free</value> </setting> <setting name="active" serializeAs="String"> <value>2026-07-15 16:38:52</value> </setting> <setting name="created_at" serializeAs="String"> <value>2026-07-15 16:38:52</value> </setting> <setting name="email" serializeAs="String"> <value>nim44r3k () gmail com</value> </setting> <setting name="fullname" serializeAs="String"> <value>AliReza Chegini</value> </setting> <setting name="subinfo" serializeAs="String"> <value>Basic</value> </setting> <setting name="usernameChanged" serializeAs="String"> <value>True</value> </setting> <setting name="rememberMe" serializeAs="String"> <value>True</value> </setting> <setting name="licenseKey" serializeAs="String"> <value>A325-****-B084-****</value> </setting> <setting name="isLoggedIn" serializeAs="String"> <value>False</value> </setting> </ezgamebooster.My.MySettings> </userSettings> </configuration> 5. Impact - Credential theft via local file read - Credential stuffing attacks on other platforms - License key theft for unauthorized activation 6. Steps to Reproduce a. Install and run EZ Game Booster v1.0.0 b. Create an account or log in c. Browse to: %LOCALAPPDATA%\ezgamebooster\ ezgamebooster_Url_fgj2qz5coiw33xftcp3agaqkgxc51bkk\1.0.0.0\ d. Open user.config with Notepad e. Observe plaintext password, email, and licenseKey 7. Remediation Encrypt sensitive data using DPAPI before serialization. Use Windows Credential Manager for credential storage. 8. Author's Note on Discovery "I discovered this while uninstalling the software and checking for leftover files. I was not performing any targeted security research at the time — I simply found my credentials in plaintext by accident."

Mitigation
Implementation System Configuration Operation

When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest. [REF-1297] [REF-1299] [REF-1301]

Mitigation
Implementation System Configuration Operation

In some systems/environments such as cloud, the use of "double encryption" (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.

CAPEC-37: Retrieve Embedded Sensitive Data

An attacker examines a target system to find sensitive data that has been embedded within it. This information can reveal confidential contents, such as account numbers or individual keys/credentials that can be used as an intermediate step in a larger attack.
