CVE-2026-72694 - Mrtg: mrtg daemon symlink-following chown allows local privilege escalation via pid file path manipulation
CVE ID :CVE-2026-72694
Published : Aug. 11, 2026, 8:37 a.m. | 50 minutes ago
Description :A flaw was found in MRTG. When the MRTG daemon is started as a root user and subsequently drops privileges, a local, low-privileged attacker can exploit a symbolic link (symlink) following vulnerability. By influencing or pre-placing a symlink in the process ID (PID) file path, the attacker can trick the root process into changing the ownership of an arbitrary existing file to the daemon user. This can lead to local privilege escalation, allowing unauthorized access to or modification of sensitive files.
Severity: 7.1 | HIGH
