A Time-of-Check Time-Of-Use vulnerability in the Trend Micro Apex One and Apex One as a Service agent could allow a local attacker to escalate privileges on affected installations.

Please note: a local attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

This is similar to, but not identical to CVE-2023-32554.

Weakness

The product checks the state of a resource before using that resource, but the resource’s state can change between the check and the use in a way that invalidates the results of the check. This can cause the product to perform invalid actions when the resource is in an unexpected state.
