Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 1.9% (FIRST EPSS); higher than 80.2% 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.
  • Fixed version: drupal7 (Debian:7) 7.14-2+deb7u12; drupal7 (Debian:8) 7.32-1+deb8u6; drupal/core (Packagist) 6.38, 7.43, 8.0.4.

Low priority for now. Upgrade to drupal7 (Debian:7) 7.14-2+deb7u12; drupal7 (Debian:8) 7.32-1+deb8u6; drupal/core (Packagist) 6.38, 7.43, 8.0.4 or later.
