CVE-2022-23805

Service crash via malformed named-pipe data

Published Feb 4, 2022 · Updated Aug 3, 2024

Out-of-bounds read in Trend Micro Worry-Free Business Security Server 10.0 SP1 allows local users to crash the server. The Smart Scan Service accepts malformed user-supplied data through a named pipe without adequate validation, causing a read past an allocated data structure. Exploitation requires low-privileged code execution on the host; direct impact is limited to information exposure and a service crash, although chained flaws can enable SYSTEM execution.
