CVE-2022-41745

Local SYSTEM code execution via NT Listener overread

Published Oct 10, 2022 · Updated Aug 3, 2024

Out-of-bounds access in Trend Micro Apex One 2019 (on-prem) and SaaS allows local users to execute code as SYSTEM via a crafted message. The Apex One NT Listener service fails to validate user-supplied message data before accessing an allocated buffer, causing an access past its end. Exploitation requires existing low-privileged code execution on an affected Windows endpoint and can elevate that code to SYSTEM.
