Technical details

An origin validation error (CWE-346) exists within the process protection mechanism of the Trend Micro Apex One and Vision One SEP agents. The vulnerability stems from insufficient verification of the source of inter-process communications or requests. To exploit this, an attacker must already have the ability to execute low-privileged code on the target Windows system. Successful exploitation allows the attacker to bypass process protections and escalate their privileges to a higher level, potentially gaining full system control. Patches have been released for both on-premises and SaaS versions of the affected products.
