CVE-2023-31322

Estado: AplazadaAlta (8.7)—

Type confusion in the ASP could allow an attacker to pass a malformed argument to the Reliability, Availability, and Serviceability trusted application (RAS TA) potentially leading to a read or write to shared memory resulting in loss of confidentiality, integrity, or availability.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L
Puntuación base: 8.7

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.14%
Percentil entre todas las CVEs puntuadas: 3
Fecha de la puntuación: 5/10/2026

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.

Impacto principalT1059 Command and Scripting Interpreterexecution75 %
Impacto secundarioT1565 Data Manipulationimpact70 %

AV:L/PR:L indica acceso local con privilegios bajos. Type confusion permite escribir en memoria compartida (impacto de integridad). Acceso a RAS TA implica ejecución de código o corrupción de datos críticos.

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.
