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.

Security readout for executives and security teams

Plain-English summary

CVE-2020-22722 is a local privilege escalation issue in Rapid SCADA 5.8.0 on Windows. A user with limited access may be able to replace the service executable and have it run with SYSTEM privileges. This can turn a foothold on a SCADA host into full host control.

Executive priority

Treat as high priority on production SCADA or monitoring servers. It requires local access, but successful abuse can give full Windows host control, increasing operational and safety risk if the host is trusted inside an industrial environment.

Technical view

The source describes ScadaAgentSvc.exe in Rapid SCADA 5.8.0 as replaceable by a local low-privileged user. When the service executable is run by Windows, the substituted binary executes as NT AUTHORITY\SYSTEM. No CVSS score, CWE, affected CPE, vendor patch, or official mitigation is provided in the bundle.

Likely exposure

Exposure appears limited to Windows systems running Rapid SCADA 5.8.0 where local users can write to the application path containing ScadaAgentSvc.exe. Evidence for other versions is not provided.

Exploitation context

The provided sources describe local privilege escalation after an attacker already has low-privileged local access. The CVE is not listed as KEV, and the bundle provides no evidence of active exploitation in the wild.

Researcher notes

The public record is sparse: one referenced advisory, no CVSS vector, no CWE, no structured affected product data, and no vendor fix details in the bundle. Validation should focus on Rapid SCADA 5.8.0 Windows deployments and filesystem permissions around ScadaAgentSvc.exe.

Mitigation direction

  • Check Rapid SCADA or vendor guidance for fixed versions or official remediation.
  • Restrict write permissions on Rapid SCADA application directories and service binaries.
  • Replace suspect service binaries from trusted installation media or known-good backups.
  • Limit local interactive access to SCADA hosts to authorized administrators.
  • Monitor for unexpected changes to ScadaAgentSvc.exe and related service paths.

Validation and detection

  • Inventory Windows hosts running Rapid SCADA 5.8.0.
  • Review NTFS permissions on the Rapid SCADA installation directory.
  • Confirm ScadaAgentSvc.exe hash and signer against trusted baseline.
  • Check Windows service configuration for unexpected binary paths.
  • Review endpoint logs for service binary replacement or suspicious SYSTEM child processes.
