CVE-2025-1445

Estado: AplazadaAlta (8.7)—

A vulnerability exists in RTU IEC 61850 client and server functionality that could impact the availability if renegotiation of an open IEC61850 TLS connection takes place in specific timing situations, when IEC61850 communication is active.

Precondition is that IEC61850 as client or server are configured using TLS on RTU500 device. It affects the CMU the IEC61850 stack is configured on.

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 red remota (AV:N, PR:N, UI:N) que afecta disponibilidad (VA:H) en servicio IEC61850 expuesto; renegociación TLS malformada causa degradación del servicio.

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.
