CVSS v3.1
Official Description
The setup_logging function in log.h in SANLock uses world-writable permissions for /var/log/sanlock.log, which allows local users to overwrite the file content or bypass intended disk-quota restrictions via standard filesystem write operations.
Technical Analysis
CVE-2012-5638 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
