CVE-2025-34140: CWE-639 Authorization Bypass Through User-Controlled Key in ETQ Reliance CG (legacy)
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.
AI Analysis
Technical Summary
This vulnerability (CVE-2025-34140) affects ETQ Reliance legacy CG and NXG SaaS platforms due to a misconfiguration in API authorization logic. By appending a crafted URI suffix to certain API endpoints, an unauthenticated attacker can bypass authorization checks and access limited sensitive resources. The root cause is improper enforcement of access control in the API layer. The vendor has corrected this issue in software versions SE.2025.1 and 2025.1.2. No known exploits are reported in the wild. The vulnerability has a high CVSS 4.0 score of 8.7, reflecting its network attack vector, low complexity, no privileges or user interaction required, and high impact on confidentiality.
Potential Impact
An unauthenticated attacker can bypass access control mechanisms and retrieve limited sensitive information from affected ETQ Reliance API endpoints. This could lead to unauthorized disclosure of sensitive data. The vulnerability does not require user interaction or privileges and can be exploited remotely over the network. There are no reports of active exploitation in the wild.
Mitigation Recommendations
A fix is available and has been implemented in ETQ Reliance versions SE.2025.1 and 2025.1.2. Users of affected versions should upgrade to these fixed versions to remediate the vulnerability. No other mitigation or temporary workaround is indicated by the vendor advisory.
