CVE-2025-2403

Estado: AplazadaAlta (8.7)—

A denial-of-service vulnerability due to improper prioritization of network traffic over protection mechanism exists in Relion 670/650 and SAM600-IO series device that if exploited could potentially cause critical functions like LDCM (Line Distance Communication Module) to malfunction.

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.

AV:N sin autenticación (PR:N) indica exposición de aplicación de red. VA:H sin confidencialidad/integridad confirma DoS. CWE-770 (asignación de recursos) y descripción de mal funcionamiento de módulos críticos sustentan T1499.

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.
