CVE-2018-9206: Unauthenticated arbitrary file upload vulnerability in Blueimp jQuery-File-Upload <= v9.22.0

CriticalCVSS 9.8 · v3.1—Weaponized Fix available

Noroxi assessment

Priority: This week (action score 68/100)

  • A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB, GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 97.2% (FIRST EPSS); higher than 99.8% 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: libjs-jquery-file-upload (Debian:12) 9.25.0-1; blueimp-file-upload (npm) 9.22.1.

Don’t wait for the next maintenance window. Upgrade to libjs-jquery-file-upload (Debian:12) 9.25.0-1; blueimp-file-upload (npm) 9.22.1 or later.
