CVE-2024-37904

Date: June 18, 2024

Minder is an open source Software Supply Chain Security Platform. Minder's Git provider is vulnerable to a denial of service from a maliciously configured GitHub repository. The Git provider clones users repositories using the "github.com/go-git/go-git/v5" library on lines "L55-L89". The Git provider does the following on the lines "L56-L62". First, it sets the "CloneOptions", specifying the url, the depth etc. It then validates the options. It then sets up an in-memory filesystem, to which it clones and Finally, it clones the repository. The "(g *Git) Clone()" method is vulnerable to a DoS attack: A Minder user can instruct Minder to clone a large repository which will exhaust memory and crash the Minder server. The root cause of this vulnerability is a combination of the following conditions: 1. Users can control the Git URL which Minder clones, 2. Minder does not enforce a size limit to the repository, 3. Minder clones the entire repository into memory. This issue has been addressed in commit "7979b43" which has been included in release version v0.0.52. Users are advised to upgrade. There are no known workarounds for this vulnerability.
