How to Fix CVE-2024-39933

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: 0.13.1 
Upgrade gogs.io/gogs to 0.13.1
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-2024-39933, 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 0.13.1), 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-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection'), where the product constructs a string for a command to be executed by a separate component in another control sphere, but it does not properly delimit the intended arguments, options, or switches within that command string. 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 Unprivileged user accounts with at least one SSH key can read arbitrary files on the system. For instance, they could leak the configuration files that could contain database credentials (`[database] *`) and `[security] SECRET_KEY`. Attackers could also exfiltrate TLS certificates, other users' repositories, and the Gogs database when the SQLite driver is enabled. ### Patches Unintended Git options has been ignored for creating tags (https://github.com/gogs/gogs/pull/7872). Users should upgrade to 0.13.1 or the latest 0.14.0+dev. ### Workarounds No viable workaround available, please only grant access to trusted users to your Gogs instance on affected versions. ### References https://www.cve.org/CVERecord?id=CVE-2024-39933
