An incorrect permission assignment denial-of-service vulnerability in Trend Micro Apex One and Apex One as a Service (SaaS) could allow a local attacker to escalate privileges and delete files with system privileges on affected installations.

Exploiting these type of vulnerabilities generally require that an attacker has access (physical or remote) to a vulnerable machine.
