CVE-2023-4759
CVSS 3.1 Score 8.8 of 10 (high)
Details
Summary
CVE-2023-4759 is a vulnerability affecting Eclipse JGit versions 6.6.0 and below. It allows an attacker to overwrite arbitrary files outside the working tree during the cloning or checkout of a malicious Git repository on case-insensitive filesystems, such as Windows and macOS. This can lead to remote code execution if the written file is a Git filter. The issue occurs when performing checkout, merge, pull, or applying a patch, and requires the user to have symbolic link creation rights and enable symbolic links in Git configuration. The vulnerability can be mitigated by setting the core.symlinks configuration option to false before checking out. Eclipse JGit versions 6.6.1 and 6.7.0, as well as a backport in 5.13.3, have been released to address this issue. The JGit maintainers acknowledge RyotaK for discovering and reporting the vulnerability.
