Noroxi assessment

Priority: Monitor (action score 29/100)

  • 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: 0.10% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: chromium (Debian:12) 152.0.7977.75-1~deb12u1; chromium (Debian:13) 152.0.7977.75-1~deb13u1; chromium (Debian:14) 152.0.7977.64-1.

Low priority for now. Upgrade to chromium (Debian:12) 152.0.7977.75-1~deb12u1; chromium (Debian:13) 152.0.7977.75-1~deb13u1; chromium (Debian:14) 152.0.7977.64-1 or later.
