Technical details

An origin validation error (CWE-346) exists within the inter-process communication (IPC) mechanism of the Trend Micro Apex One and Vision One Standard Endpoint Protection (SEP) agents. The vulnerability stems from insufficient verification of the source of IPC requests, allowing a local attacker who has already obtained low-privileged code execution to send crafted messages to the agent. By exploiting this flaw, the attacker can achieve local privilege escalation (LPE) on the affected Windows installation. Trend Micro has released patches for both on-premises and SaaS versions of the product to address this issue.
