Use After Free and Heap-based Buffer Overflow and Integer Overflow or Wraparound and Out-of-bounds Write in iccDEV

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: InternationalColorConsortium iccDEV 2.3.1.2.

Low priority for now. Upgrade to InternationalColorConsortium iccDEV 2.3.1.2 or later.
