CVE-2022-28339

Local privilege escalation via unsecured scanner load

Published Feb 22, 2025 · Updated Feb 24, 2025

Uncontrolled search path in Trend Micro HouseCall for Home Networks before 5.3.1308 allows local users to execute code as an administrator. The log4j scanner process loads a file from an unsecured location, allowing a low-privileged user to place a malicious DLL for privileged loading. Exploitation requires local low-privileged code execution and user interaction; successful exploitation runs arbitrary code with administrator privileges.
