CVE-2024-56731: Gogs allows deletion of internal files which leads to remote command execution

Should you act?

Critical and remotely reachable

No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
• EPSS 1.1%, percentile 67: FIRST’s model estimates a 1.1% chance of exploitation activity in the next 30 days, higher than 67% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes gogs.io/gogs (Go) <= 0.13.2, fixed in 0.13.3. Check your lockfile, including transitive dependencies.

What it is

Gogs is an open source self-hosted Git service. Prior to version 0.13.3, it's still possible to delete files under the .git directory and achieve remote command execution due to an insufficient patch for CVE-2024-39931. Unprivileged user accounts can execute arbitrary commands on the Gogs instance with the privileges of the account specified by RUNUSER in the configuration. Allowing attackers to access and alter any users' code hosted on the same instance. This issue has been patched in version 0.13.3.

From the GitHub advisory

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

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 RUNUSER in the configuration. It allows attackers to access and alter any users' code hosted on the same instance.

Weakness type: CWE-552.
