MediumCVSS 5.0 · v2.0—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 6% (FIRST EPSS); higher than 93.4% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: openssh (Debian:12) 1:3.9p1-1.

Low priority for now. Upgrade to openssh (Debian:12) 1:3.9p1-1 or later.
