CVE-2022-36336

SYSTEM code execution via mount-point folder deletion

Published Jul 29, 2022 · Updated Aug 3, 2024

Link following in Trend Micro Apex One 2019 and SaaS and Worry-Free Business Security 10.0 SP1 and SaaS allows local users to gain SYSTEM privileges. In Apex One, the NT Apex One RealTime Scan Service follows an attacker-created mount point and deletes the redirected folder; Trend Micro attributes the same scanning flaw to Worry-Free. Low-privileged code execution on an affected Windows endpoint is required, and successful exploitation runs arbitrary code as SYSTEM.
