HighCVSS 7.8 · v3.0—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.2% (FIRST EPSS); higher than 68.9% of all records.
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: systemd (Debian:12) 229-1; systemd (openSUSE:Tumbleweed) 249.4-2.2; systemd (SUSE:Linux Enterprise Desktop 12 SP2) 228-132.1.

Low priority for now. Upgrade to systemd (Debian:12) 229-1; systemd (openSUSE:Tumbleweed) 249.4-2.2; systemd (SUSE:Linux Enterprise Desktop 12 SP2) 228-132.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw in systemd v228 in /src/basic/fs-util.c caused world writable suid files to be created when using the systemd timers features, allowing local attackers to escalate their privileges to root. This is fixed in v229.
