ExploitCVE-2024-7962
Path Traversal: '\..\filename' (CWE-29)
Summary
An arbitrary file read vulnerability exists in gaizhenbiao/chuanhuchatgpt version 20240628 due to insufficient validation when loading prompt template files. This vulnerability allows an attacker to read any file that matches specific criteria using an absolute path. The file must not have a .json extension and, except for the first line, every other line must contain commas. This vulnerability allows reading parts of format-compliant files, including code and log files, which may contain highly sensitive information such as account credentials.
Impact
This vulnerability allows attackers to read sensitive information from affected systems. Attacks exploiting this vulnerability could lead to unauthorized access to sensitive data, including account credentials found in code and log files. This could potentially lead to further compromise of the system or related accounts. The confidentiality impact is rated as HIGH, while integrity and availability impacts are NONE, indicating that the primary concern is data exposure rather than system modification or disruption.
Exploitation
One proof-of-concept exploit is available on huntr.com. There is no evidence of proof of exploitation at the moment.
Patch
A patch is available. The vulnerability was addressed in a commit on GitHub on October 31, 2024. The patch can be found at: https://github.com/gaizhenbiao/chuanhuchatgpt/commit/2836fd1db3efcd5ede63c0e7fbbdf677730dbb51
Mitigation
1. Update gaizhenbiao/chuanhuchatgpt to a version later than 20240628 that includes the security patch. 2. Implement strict input validation for file paths, ensuring that only intended directories and files can be accessed. 3. Use a whitelist approach for allowed file types and locations. 4. Implement proper access controls to sensitive files and directories. 5. Regularly audit and monitor system logs for any suspicious file access attempts. 6. Consider implementing additional security layers such as Web Application Firewalls (WAF) to help detect and prevent path traversal attacks.
