System Informer before 4.0.26241.138 contains an incorrect authorization vulnerability in the phsvc helper that allows local attackers to reach privileged APIs by connecting from any Authenticode-signed process. Attackers can load code into a Microsoft-signed host like rundll32.exe, connect to SiSvcApiPort, and call PhSvcApiCreateService to execute code as SYSTEM.
