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.
