CVE-2026-9634: Redundancy Module Configuration Tool - Multiple Vulnerabilities
A security issue exists within the Redundancy Module Configuration Tool. The RMConfigTool.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.

Event History
Frequently Asked Questions
Who is exposed to this issue?
Systems are exposed where one or more directories searched through the system path are writable by standard non-administrator users and an administrator runs RMConfigTool.exe. The attacker needs local access to place a malicious DLL in a writable searched directory.
Does exploitation require administrator interaction?
Yes. A local attacker can place the malicious DLL, but an administrator must subsequently run the tool for the DLL to be loaded into the elevated process.
What is the impact if exploitation succeeds?
The malicious DLL executes in the elevated RMConfigTool.exe process with Administrator or SYSTEM privileges.
