Gurock TestRail Application files.md5 Exposure (CVE-2021-40875)

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 which can then be tested, and in some cases result in the disclosure of hardcoded credentials, API keys, or other sensitive data.

Gurock TestRail版本低于7.2.0.3014存在不当访问控制问题，导致敏感信息泄露。攻击者可访问Gurock TestRail应用客户端的/files.md5文件，从而披露完整的应用文件列表及其对应的文件路径，进而进行测试。在某些情况下，还可能导致硬编码凭证、API密钥或其他敏感数据的泄露。
