ETQ Reliance CG/NXG API Authorization Bypass via ;localized-text URI Suffix

An authorization bypass vulnerability exists in ETQ Reliance (legacy CG and NXG SaaS platforms). By appending a specific URI suffix to certain API endpoints, an unauthenticated attacker can bypass access control checks and retrieve limited sensitive resources. The root cause was a misconfiguration in API authorization logic, which has since been corrected in SE.2025.1 and 2025.1.2.

Reliance 4 SCADA/HMI, Version 4.7.3 Update 3 and prior. This vulnerability could allow an unauthorized attacker to inject arbitrary code.
