Technical details

A Time-of-Check Time-of-Use (TOCTOU) race condition exists within the cache mechanism of the Trend Micro Apex One (mac) Security Agent. The vulnerability stems from a lack of proper cache key validation during signature verification processes. A local attacker with low-privileged code execution capabilities can exploit this flaw to manipulate the cache, leading to arbitrary code execution with root privileges. The issue was addressed in the SaaS 2507 and 2005 Yearly Release updates via ActiveUpdate.
