Noroxi assessment

Priority: Plan (action score 50/100)

  • 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: 41.7% (FIRST EPSS); higher than 98.7% of all records.
  • Fixed version: wireshark (Debian:12) 1.4.5-1.

Add it to your regular patch cycle. Upgrade to wireshark (Debian:12) 1.4.5-1 or later.
