Noroxi assessment

Priority: Monitor (action score 39/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.1% (FIRST EPSS); higher than 66% 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: statamic cms 3.4.13.

Low priority for now. Upgrade to statamic cms 3.4.13 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Statmic is a core Laravel content management system Composer package. Prior to versions 3.4.13 and 4.33.0, on front-end forms with an asset upload field, PHP files crafted to look like images may be uploaded. This only affects forms using the "Forms" feature and not just _any_ arbitrary form. This does not affect the control panel. This issue has been patched in 3.4.13 and 4.33.0.
