ZDI-26-987: Trend AI Vision One Security Agent TMBMServer Type Confusion Local Privilege Escalation Vulnerability
Summary: The Zero Day Initiative published ZDI-26-987, a type confusion flaw in the Trend Micro Unauthorized Change Prevention Service within TrendAI Vision One Security Agent that lets a local attacker with low-privileged code execution escalate to SYSTEM. The issue stems from missing validation of user-supplied data, and TrendAI has issued an update to correct it.
What you should know: The flaw sits in the security agent itself, so the software installed to protect endpoints becomes the path to SYSTEM-level code execution for anyone who already has a low-privileged foothold.
