TrendAI Vision One Security Agent Stack-based Buffer Overflow Local Privilege Escalation Vulnerability
Vulnerability Details
This vulnerability allows local attackers to escalate privileges on affected installations of TrendAI Vision One Security Agent. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the Apex One NT RealTime Scan service. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-size stack-based buffer. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.
