HighCVSS 7.8 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

  • 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: 4.3% (FIRST EPSS); higher than 91.3% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: p7zip (Alpine:v3.10) 16.02-r3; p7zip-rar (Debian:12) 16.02-3.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to p7zip (Alpine:v3.10) 16.02-r3; p7zip-rar (Debian:12) 16.02-3 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Incorrect initialization logic of RAR decoder objects in 7-Zip 18.03 and before can lead to usage of uninitialized memory, allowing remote attackers to cause a denial of service (segmentation fault) or execute arbitrary code via a crafted RAR archive.
