02 Description
Mrtg: mrtg daemon symlink-following chown allows local privilege escalation via pid file path manipulation
03 Exploitation and scoring
- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
- EPSS probability
- 0.13% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Equal to or higher than the score of 3.0% of scored records. A rank, not a probability.
- NVD base score
- 7.1 (CVSS v3.x), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N
- NVD analysis status
- Awaiting Analysis. NVD last modified this record on 2026-10-28.
- Red Hat severity
