CVE-2025-71255

Estado: AnalizadaAlta (7.5)—

In Modem IMS, there is a possible improper input validation. This could lead to remote denial of service with no additional execution privileges needed.

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.

Vector AV:N/AC:L/PR:N/UI:N con impacto A:H indica explotación remota sin privilegios (T1190). La descripción de 'remote denial of service' por validación impropia en Modem IMS se mapea a T1499.004 (Application Exhaustion).

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.
