Estado: En análisisAlta (8.8)—

IBM MQ could allow an authenticated attacker to cause a denial of service or potentially execute arbitrary code due to improper validation of message distribution list structures.

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 con PR:L indica explotación de servicio remoto autenticado (T1210). La descripción sugiere ejecución arbitraria de código (T1059) y negación de servicio (T1499.004) por validación deficiente en MQ.

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.
