Priority: Monitor (action score 35/100)
- 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: 15.3% (FIRST EPSS); higher than 96.8% of all records.
- No special conditions are required; it is repeatable.
- Fixed version: apache2 (Debian:12) 2.0.52-2; httpd (Red Hat:enterprise_linux:3::as) 0:2.0.46-44.ent; httpd-debuginfo (Red Hat:enterprise_linux:3::as) 0:2.0.46-44.ent.
