CVE-2021-40875: n/a vulnerability

CVE-2021-40875: Improper Access Control in Gurock TestRail versions < 7.2.0.3014 resulted in sensitive information exposure.

Improper Access Control in Gurock TestRail versions < 7.2.0.3014 resulted in sensitive information exposure. A threat actor can access the /files.md5 file on the client side of a Gurock TestRail application, disclosing a full list of application files and the corresponding file paths. The corresponding file paths can be tested, and in some cases, result in the disclosure of hardcoded credentials, API keys, or other sensitive data.

Security readout for executives and security teams

Older Gurock TestRail deployments could expose a file manifest that reveals application file paths. Attackers may use that information to find files that unintentionally contain credentials, API keys, or other sensitive data. The source bundle does not provide CVSS scoring or confirmed active exploitation. Exposure is most likely where TestRail is internet-facing or reachable by untrusted users and is running a version below 7.2.0.3014. Risk depends on whether the exposed paths lead to sensitive files in that specific deployment. Prioritize if TestRail is externally reachable or stores sensitive operational data. The main business risk is credential or API key leakage that can enable broader compromise beyond TestRail. Mitigation focus: Inventory all TestRail instances and confirm their exact versions.; Upgrade affected TestRail deployments to a vendor-confirmed non-affected release.; Restrict external access to TestRail where business needs allow..
