SYSTEM code execution via mispermissioned service resource
Published Apr 13, 2021 · Updated Aug 3, 2024
Incorrect permission assignment in Trend Micro Apex One 2019, SaaS, and OfficeScan XG SP1 allows local users to gain SYSTEM privileges. The ApexOne Security Agent sets incorrect permissions on a resource used by its service, allowing attacker-controlled code to execute as SYSTEM. Exploitation requires prior low-privileged code execution on an affected Windows endpoint; the specific service resource is not publicly identified.
