CVE-2026-9633

A security issue exists within the Redundancy Module Configuration Tool. The RM3ConfigTool.exe binary searches directories in the system path for a required DLL, and one or more of these directories may be writable by standard (non-administrator) users due to incorrect default permissions. If a local attacker places a malicious DLL in such a directory and an administrator subsequently runs the tool, the malicious DLL is loaded into the elevated process and executes with Administrator/SYSTEM privileges.
