CVE-2025-54630

Estado: AnalizadaAlta (7.5)—

:Vulnerability of insufficient data length verification in the DFA module. Impact: Successful exploitation of this vulnerability may affect availability.

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/AC:L/PR:N sin UI indica explotación remota sin autenticación (T1190). CWE-122 (buffer overflow) en módulo DFA con A:H sugiere DoS por agotamiento de recursos (T1499.004).

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.
