SYSTEM code execution via unchecked stack copy
Published Oct 21, 2021 · Updated Aug 4, 2024
Stack-based buffer overflow in Trend Micro Apex One 2019 and SaaS and Worry-Free Business Security 10.0 SP1 allows local users to gain SYSTEM. In Worry-Free Business Security, the Security Server Database Service copies user-supplied data into a stack buffer without first validating its length; the corresponding Apex One locus is undisclosed. A low-privileged local session is required, and successful exploitation executes arbitrary code as SYSTEM on the Windows host.
