Noroxi assessment

Priority: Plan (action score 59/100)

  • A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 95.2% (FIRST EPSS); higher than 99.8% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: apache2 (Debian:12) 2.0.37.

Add it to your regular patch cycle. Upgrade to apache2 (Debian:12) 2.0.37 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Apache 1.3 through 1.3.24, and Apache 2.0 through 2.0.36, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a chunk-encoded HTTP request that causes Apache to use an incorrect size.
