EUVDB-ID: #VU72246

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2023-22490

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to insecure processing of symbolic links when using local clone optimization. Git will abort local clones whose source `$GIT_DIR/objects` directory contains symbolic links, however the `objects` directory itself may still be a symbolic link. A remote attacker can trick the victim into using the local clone optimization to exfiltrate arbitrary files from the victim's system.

Mitigation

Install update from vendor's website.
