CVE-2026-82335

Estado: AnalizadaCrítica (9.8)—

IBM Guardium Data Protection 12.0, 12.1, 12.2 es vulnerable a un desbordamiento de búfer basado en montículo (heap) en el analizador del protocolo MongoDB. Un atacante remoto podría enviar un nombre de usuario SCRAM de MongoDB especialmente manipulado con una longitud excesiva y provocar corrupción de memoria, lo que podría dar lugar a una denegación de servicio o a la ejecución de código arbitrario.

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:H/PR:N/UI:N indica explotación remota sin autenticación (T1190). Heap overflow en parser MongoDB permite ejecución de código (T1059) o DoS (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.
