When dealing with abnormally constructed objects, there is a lack of argument validation; JavaScript triggers signature verification, but the signature plugin does not perform validation when copying the abnormal string, causing the application to crash.

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 AV:L/UI:R indica ejecución en cliente (abrir PDF manipulado). CWE-120 (buffer overflow) en Foxit al procesar objetos anormales. Impacto: ejecución de código (JavaScript mencionado) y DoS (application crash).

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.
