Noroxi assessment

Priority: This week (action score 60/100)

  • 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: 78% (FIRST EPSS); higher than 99.5% of all records.
  • Fixed version: zope2 (PyPI) 2.12.20, 2.13.10.

Don’t wait for the next maintenance window. Upgrade to zope2 (PyPI) 2.12.20, 2.13.10 or later.
