ZDI-26-986: Trend AI Vision One Security Agent TMBMServer Type Confusion Local Privilege Escalation Vulnerability
Summary: ZDI-26-986 describes a type confusion flaw in the Trend Micro Unauthorized Change Prevention Service of TrendAI Vision One Security Agent, caused by a lack of proper validation of user-supplied data. An attacker who can first run low-privileged code locally can exploit it to escalate privileges and execute arbitrary code as SYSTEM; TrendAI has issued an update, credited to Lays (@_L4ys) of TRAPA Security.
Bottom line: The flaw sits inside the security agent itself, and successful exploitation ends in SYSTEM-level code execution, so the tool meant to protect the endpoint becomes the path to its highest privilege level.
