MediumCVSS 5.5 · v4.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.70% (FIRST EPSS); higher than 53.9% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: 7zip (Debian:12) 22.01+really25.01+dfsg-0+deb12u1; p7zip (Debian:12) 16.02+really25.01+dfsg-0+deb12u1; 7zip (Debian:13) 25.00+dfsg-1.

Low priority for now. Upgrade to 7zip (Debian:12) 22.01+really25.01+dfsg-0+deb12u1; p7zip (Debian:12) 16.02+really25.01+dfsg-0+deb12u1; 7zip (Debian:13) 25.00+dfsg-1 or later.
