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.
