CVE-2026-82344

Estado: AnalizadaCrítica (9.8)—

IBM Guardium Data Protection 12.0, 12.1 es vulnerable a un desbordamiento de búfer basado en montículo (heap) en la funcionalidad de reensamblado de inicio de sesión TDS de S-TAP TrafficTap. Un atacante remoto no autenticado puede enviar fragmentos de inicio de sesión TDS manipulados que superen el búfer de reensamblado de tamaño fijo, lo que podría provocar una denegación de servicio o la ejecución de código arbitrario en el sistema afectado.

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.

Buffer overflow remoto en TDS login sin autenticación (AV:N, PR:N, UI:N) permite ejecución de código arbitrario o DoS; vector CVSS HIGH confirma severidad. CWE-119 (buffer overflow) tipifica ejecución de código.

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.
