Vulnerability from github – Published: 2023-02-28 20:12 – Updated: 2023-03-09 15:31

Summary

Gogs OS Command Injection vulnerability

Details

Impact

The malicious user is able to update a crafted config file into repository's .git directory in combination with crafted file deletion to gain SSH access to the server on case-insensitive file systems. All installations with repository upload enabled (default) on case-insensitive file systems (Windows, macOS, etc.) are affected.

Patches

Make sanitization of upload path to .git directory to be case-insensitive. Users should upgrade to 0.12.11 or the latest 0.13.0+dev.

Workarounds

Disable repository upload.
