How to Fix CVE-2022-2024

To remediate this vulnerability, upgrade all affected Gogs.io/gogs dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

gogs.io/gogs fixed: 0.12.11 
Upgrade gogs.io/gogs to 0.12.11
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for gogs.io/gogs

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-2024, inspect your project dependencies for Gogs.io/gogs:

inspect dependencies for gogs.io/gogs

Analyze the terminal output to locate any version of Gogs.io/gogs in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.11), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'), where the product constructs all or part of an os command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended os command when it is sent to a downstream component. In Gogs.io/gogs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
