CVE-2026-66344

SYSTEM code execution via writable DLL search path

Published Aug 5, 2026 · Updated Aug 5, 2026

DLL search-path hijacking in NetKids iMark 5.2.5.0 and earlier allows local users to execute arbitrary code as SYSTEM. Privileged iMark components search for DLLs in the installation directory, whose access controls allow authenticated users to place files there. A user able to log on locally and write a malicious DLL to that directory can have it loaded when an affected component runs, gaining SYSTEM privileges.
