Noroxi assessment

Priority: Monitor (action score 27/100)

  • 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: 2.5% (FIRST EPSS); higher than 85.3% 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: libgd2 (Debian:12) 2.2.2-29-g3c2b605-1; libgd2 (Debian:8) 2.1.0-5+deb8u4; gd (openSUSE:Tumbleweed) 2.2.3-2.1.

Low priority for now. Upgrade to libgd2 (Debian:12) 2.2.2-29-g3c2b605-1; libgd2 (Debian:8) 2.1.0-5+deb8u4; gd (openSUSE:Tumbleweed) 2.2.3-2.1 or later.
