CVE-2024-24765: 
vulnerability analysis and mitigation

CasaOS-UserService, which provides user management functionalities to CasaOS, contains a path traversal vulnerability (CVE-2024-24765) that was disclosed on March 6, 2024. The vulnerability affects versions prior to 0.4.6 of the CasaOS-UserService package. This security flaw allows unauthorized access to arbitrary files on the system through the user image endpoint (GitHub Advisory).

The vulnerability exists in the user image endpoint of CasaOS-UserService where insufficient path filtering allows attackers to access files outside the intended directory. The issue stems from inadequate validation of the path parameter in the image retrieval functionality. The vulnerability has been assigned a CVSS v3.1 score of 9.8 (CRITICAL), indicating its severe nature (NVD).

The vulnerability allows attackers to access any file on the system, including sensitive files such as the CasaOS user database. This access could potentially lead to obtaining system root privileges, significantly compromising the system's security (GitHub Advisory).

The vulnerability has been patched in version 0.4.7 of CasaOS-UserService. The fix includes implementing proper path validation to restrict access to authorized files only. Users are strongly advised to upgrade to version 0.4.7 or later to mitigate this security risk (GitHub Release).
