Noroxi assessment
Priority: Plan (action score 51/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 39.3% (FIRST EPSS); higher than 98.6% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: apache2 (Alpine:v3.10) 2.4.26-r0; apache2 (Debian:12) 2.4.25-4; apache2 (Debian:7) 2.2.22-13+deb7u9.
Add it to your regular patch cycle. Upgrade to apache2 (Alpine:v3.10) 2.4.26-r0; apache2 (Debian:12) 2.4.25-4; apache2 (Debian:7) 2.2.22-13+deb7u9 or later.
