Detailsinfo

A vulnerability, which was classified as critical, was found in Ericsson CodeChecker up to 6.22.x. This affects an unknown code of the file /Default/v6.53/CodeCheckerService@massStoreRun of the component ZIP File Handler. The manipulation with an unknown input leads to a path traversal vulnerability. CWE is classifying the issue as CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. This is going to have an impact on confidentiality. The summary by CVE is:

CodeChecker is an analyzer tooling, defect database and viewer extension for the Clang Static Analyzer and Clang Tidy. Zip files uploaded to the server endpoint of `CodeChecker store` are not properly sanitized. An attacker, using a path traversal attack, can load and display files on the machine of `CodeChecker server`. The vulnerable endpoint is `/Default/v6.53/CodeCheckerService@massStoreRun`. The path traversal vulnerability allows reading data on the machine of the `CodeChecker server`, with the same permission level as the `CodeChecker server`. The attack requires a user account on the `CodeChecker server`, with permission to store to a server, and view the stored report. This vulnerability has been patched in version 6.23.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2023-49793 since 11/30/2023. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1006 for this issue.
