Name of the Vulnerable Software and Affected Versions Trend Micro Apex One (mac) agent (affected versions not specified)

Description A time-of-check time-of-use (TOCTOU) issue exists in the cache mechanism of the Trend Micro Apex One (mac) agent. A TOCTOU is a race condition where a system checks a condition (such as a file's existence or permissions) and then uses the result of that check, but the condition changes between the check and the use. This could allow a local attacker, who already has the ability to execute low-privileged code on the target system, to escalate their privileges.

Recommendations Update the agent via ActiveUpdate or SaaS updates (SaaS 2507 & 2005 Yearly Release).
