  • Vulnerability involves improper handling of COM object creation by the Windows COM Server, enabling elevation of privilege via a specially crafted application run by a local attacker.
  • Attack requires local logon; monitor for unusual COM object instantiation from low-privileged processes or unexpected child processes spawned with elevated privileges.
  • ·No public exploit code or proof-of-concept has been disclosed as of the advisory; exploitation assessed as 'Less Likely' for both latest and older software releases.
  • ·The fix corrects how the Windows COM Server creates COM objects; patched systems are addressed by KB updates including KB4565503, KB4565489, KB4558998, KB4565483, and KB4565508.
