Estado: AnalizadaAlta (8.8)—

Dell Update Package Framework, versions prior to 26.07.03, contains a Stack-based Buffer Overflow vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Remote execution.

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 en servicio de red (CWE-121) con AV:A sin autenticación permite ejecución remota de código en sistema adyacente de la red.

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.
