Noroxi assessment

Priority: Monitor (action score 24/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Probability of exploitation in the next 30 days: 3.4% (FIRST EPSS); higher than 88.9% of all records.
  • Fixed version: awstats (Debian:12) 6.9.5~dfsg-1.

Low priority for now. Upgrade to awstats (Debian:12) 6.9.5~dfsg-1 or later.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
