CVE-2026-12351

Estado: Pendiente de análisisCrítica (9.8)—

IBM MQ 9.3.0.0 through 9.3.0.41 LTS, 9.3.0.0 through 9.3.5.1 CD, 9.4.0.0 through 9.4.0.25 LTS, 9.4.0.0 through 9.4.5.1 LTS, and 10.0.0.0 could allow a remote attacker to execute arbitrary code due to unsafe JNDI lookup processing when the IVT application is deployed.

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 CVSS AV:N/AC:L/PR:N/UI:N indica vulnerabilidad remota sin privilegios ni interacción (T1190). JNDI lookup inseguro en IBM MQ permite ejecución arbitraria de código (T1059) y potencial acceso a cuentas/credenciales del servicio (T1078).

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.
