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% (FIRST EPSS); higher than 81.3% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: php5 (Debian:4.0) 5.2.0-8+etch9; php5 (Debian:5.0) 5.2.3-1+lenny1; php (Red Hat:enterprise_linux:3::as) 0:4.3.2-43.ent.

Low priority for now. Upgrade to php5 (Debian:4.0) 5.2.0-8+etch9; php5 (Debian:5.0) 5.2.3-1+lenny1; php (Red Hat:enterprise_linux:3::as) 0:4.3.2-43.ent or later.
