CVE-2024-37904

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
