CVE-2020-11493

Estado: ModificadaAlta (8.1)—💥 PoC

In Foxit Reader and PhantomPDF before 10.0.1, and PhantomPDF before 9.7.3, attackers can obtain sensitive information about an uninitialized object because of direct transformation from PDF Object to Stream without concern for a crafted XObject.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
