CVE-2022-2024

### 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)](https://github.com/gogs/gogs/blob/f36eeedbf89328ee70cc3a2e239f6314f9021f58/conf/app.ini#L127-L129) 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](https://github.com/gogs/gogs/blob/f36eeedbf89328ee70cc3a2e239f6314f9021f58/conf/app.ini#L127-L129). ### References https://huntr.dev/bounties/18cf9256-23ab-4098-a769-85f8da130f97/ ### For more information If you have any questions or comments about this advisory, please post on https://github.com/gogs/gogs/issues/7030.
