SB2024090690 - Improper Resolution of Path Equivalence in gix-path

Description

This security bulletin contains information about 1 vulnerability.

1) Improper Resolution of Path Equivalence (CVE-ID: CVE-2024-45405)

CWE-ID: CWE-41 - Improper Resolution of Path Equivalence

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green

The vulnerability allows a local user to execute arbitrary code.

The vulnerability exists due to improper resolution of path equivalence in gix_path::env installation_config and installation_config_prefix when parsing the path reported by git config -l --show-origin. A local user can create a crafted configuration path that is resolved to an attacker-controlled file to execute arbitrary code.

User interaction is required, and exploitation is only plausible in uncommon multi-user or unusually configured environments.

Remediation

Install update from vendor's website.
