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.
