This vulnerability involves the RMConfigTool.exe binary which searches system directories for a required DLL. Due to incorrect default permissions, standard users can write to these directories. An attacker can place a malicious DLL in such a directory. When an administrator runs the tool, the malicious DLL loads and executes with elevated privileges.
