HighCVSS 7.5 · v2.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 2.4% (FIRST EPSS); higher than 84.8% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: libxml2 (Debian:12) 2.7.8.dfsg-7; libxml2 (Debian:5.0) 2.6.32.dfsg-5+lenny5; libxml2 (Debian:6.0) 2.7.8.dfsg-2+squeeze2.

Low priority for now. Upgrade to libxml2 (Debian:12) 2.7.8.dfsg-7; libxml2 (Debian:5.0) 2.6.32.dfsg-5+lenny5; libxml2 (Debian:6.0) 2.7.8.dfsg-2+squeeze2 or later.
