How to Fix CVE-2024-56731

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: 0.13.3 
Upgrade gogs.io/gogs to 0.13.3
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-2024-56731, 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 0.13.3), 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-552: Files or Directories Accessible to External Parties, where the product makes files or directories accessible to unauthorized actors, even though they should not be. 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

### Summary Due to the insufficient patch for the CVE-2024-39931, it's still possible to delete files under the `.git` directory and achieve remote command execution. ### Details In the patch for CVE-2024-39931, the following check is added: https://github.com/gogs/gogs/commit/77a4a945ae9a87f77e392e9066b560edb71b5de9 ```diff + // 🚨 SECURITY: Prevent uploading files into the ".git" directory + if isRepositoryGitPath(opts.TreePath) { + return errors.Errorf("bad tree path %q", opts.TreePath) + } ``` While the above code snippet checks if the specified path is a `.git` directory, there are no checks for symbolic links in the later steps. So, by creating a symbolic link that points to the `.git` directory, an attacker can still delete arbitrary files in the `.git` directory and achieve remote command execution. ### Impact Unprivileged user accounts can execute arbitrary commands on the Gogs instance with the privileges of the account specified by `RUN_USER` in the configuration. It allows attackers to access and alter any users' code hosted on the same instance.
