Noroxi assessment

Priority: This week (action score 73/100)

  • CISA has confirmed exploitation in the wild (Nov 30, 2023). Remediation deadline for US federal agencies: Dec 21, 2023.
  • Probability of exploitation in the next 30 days: 16.4% (FIRST EPSS); higher than 96.9% of all records.
  • Anyone who can reach it over the internet 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.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: chromium (Debian:11) 119.0.6045.199-1~deb11u1; chromium (Debian:12) 119.0.6045.199-1~deb12u1; chromium (Debian:13) 119.0.6045.199-1.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to chromium (Debian:11) 119.0.6045.199-1~deb11u1; chromium (Debian:12) 119.0.6045.199-1~deb12u1; chromium (Debian:13) 119.0.6045.199-1 or later.
