AI-suggested
To mitigate CVE-2025-27614, European organizations should immediately upgrade all gitk installations to the latest patched versions (2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, or 2.50.1). Organizations should audit their environments to identify all instances of gitk and verify version compliance. Implement strict policies to avoid cloning and inspecting Git repositories from untrusted or unknown sources. Educate developers and users about the risks of opening repositories and files from unverified origins, emphasizing caution when invoking gitk with filenames. Employ endpoint protection solutions capable of detecting suspicious script execution triggered by gitk. Consider restricting the use of gitk to isolated or sandboxed environments where possible. Additionally, monitor logs for unusual gitk usage patterns or unexpected script executions. Incorporate this vulnerability into vulnerability management and patching workflows to ensure timely updates. For critical environments, consider disabling gitk temporarily until patched versions are deployed.
Description
Gitk is a Tcl/Tk based Git history browser. Starting with 2.41.0, a Git repository can be crafted in such a way that with some social engineering a user who has cloned the repository can be tricked into running any script (e.g., Bourne shell, Perl, Python, ...) supplied by the attacker by invoking gitk filename, where filename has a particular structure. The script is run with the privileges of the user. This vulnerability is fixed in 2.43.7, 2.44.4, 2.45.4, 2.46.4, 2.47.3, 2.48.2, 2.49.1, and 2.50.
