CVE-2025-34140

Estado: AplazadaAlta (8.7)—

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.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad de autorización en API remota (AV:N, PR:N, UI:N) explotable sin autenticación para acceder a recursos sensibles. CWE-639 indica fallo de control de acceso que permite lectura de datos.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
