CVE-2024-9247

Estado: AnalizadaAlta (7.8)—

Foxit PDF Reader Annotation Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

The specific flaw exists within the handling of Annotation objects. The issue results from the lack of proper validation of user-supplied data, which can result in a write before the start of an allocated object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24173.

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 CVSS con UI:R (interacción del usuario requerida) y AV:L (acceso local). Descripción explícita: "debe visitar una página maliciosa o abrir un archivo malicioso". Out-of-bounds write en objetos Annotation de PDF permite ejecución de código arbitrario en el contexto del proceso, sin requerir es

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.
