When scripts triggered document modifications, object reference validity was not properly maintained, leading to a crash when accessing an invalid pointer during page information queries.

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.

AV:L + UI:R (abrir PDF preparado) → T1203. Corrupción de memoria (CWE-416, use-after-free) permite ejecución de código arbitrario en el contexto del proceso Foxit.

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.
