CVE-2019-4013· NVD / CVE Program· CNA ibm

IBM BigFix Platform 9.5 could allow any authenticated user to upload any file to any location on the server with root privileges.

Noroxi assessment

Priority: Plan (action score 43/100)

  • 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: 13% (FIRST EPSS); higher than 96.3% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to the record, no fixed version is available yet.

Add it to your regular patch cycle. Update when a fix is released; follow the vendor's advisory.
