Description

Rapid Software LLC Rapid SCADA 5.8.0 is affected by a local privilege escalation vulnerability in the ScadaAgentSvc.exe executable file. An attacker can obtain admin privileges by placing a malicious .exe file in the application and renaming it ScadaAgentSvc.exe, which would result in executing the binary as NT AUTHORITY\SYSTEM in a Windows operating system. For example, an attacker can plant a reverse shell from a low privileged user account and by restarting the computer, the malicious service will be started as NT AUTHORITY\SYSTEM by giving the attacker full system access to the remote PC.
