HighCVSS 7.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Plan (action score 55/100)

  • 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: 82.3% (FIRST EPSS); higher than 99.6% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: nginx (Debian:12) 1.9.10-1; nginx (Debian:6.0) 0.7.67-3+squeeze4+deb6u1; nginx (Debian:7) 1.2.1-2.2+wheezy4.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Add it to your regular patch cycle. Upgrade to nginx (Debian:12) 1.9.10-1; nginx (Debian:6.0) 0.7.67-3+squeeze4+deb6u1; nginx (Debian:7) 1.2.1-2.2+wheezy4 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The resolver in nginx before 1.8.1 and 1.9.x before 1.9.10 allows remote attackers to cause a denial of service (invalid pointer dereference and worker process crash) via a crafted UDP DNS response.
