Summary
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.
Exploit prediction
0.46% chance of exploitation in the next 30 days, higher than 39% of all scored CVEs (FIRST EPSS, 2026-11-08).
