Short explanation
A remote code execution vulnerability exists in the GitPython library because create_submodule() validates submodule paths only after cloning.
This flaw allows attackers to plant executable post-checkout hooks on target systems and execute code during subsequent Git operations.
What should be done?
- Update the GitPython library
- Follow vendor security advisories
- Validate untrusted submodule paths
Chain of evidence and sources
GitPython 3.2.1 öncesi sürümlerde create_submodule() fonksiyonu alt modül yollarını klonlama sonrasında doğrular.
Saldırganlar bu açığı kullanarak yürütülebilir post-checkout kancaları yerleştirebilir.
Show the technical text from the sources
GitPython is a python library used to interact with Git repositories. Prior to 3.2.1, create_submodule() in git/objects/submodule/base.py accepts an attacker-influenced submodule path such as .git/hooks and invokes _clone_repo() before safely rejecting the destination. In 3.1.x, _validate_repo_path() does not exist and the call succeeds silently, while in 3.2.0 and later affected revisions the check in git/index/base.py raises ValueError only after the clone has written to disk and does not remove the planted file. An attacker-controlled submodule can therefore place an executable post-checkout hook that a later Git operation executes. Exploitation requires an application to accept an untrusted submodule path and a clone destination such as .git/hooks that is empty enough for Git to clone into it, which commonly means that default sample hooks are absent. This issue is fixed in version 3.2.1.
