CVE-2020-37254

Estado: Pendiente de análisisAlta (8.5)—

Wondershare PDFelement 5.2.9 contains a privilege escalation vulnerability due to an unquoted service path in the WsAppService Windows service. Local attackers can place a malicious executable in the service path and execute code with LocalSystem privileges upon service restart or system reboot.

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/PR:L/UI:N indica escalada local sin interacción: T1068. El atacante logra ejecución de código con privilegios LocalSystem mediante ruta sin entrecomillas en servicio Windows, permitiendo ejecutar comandos arbitrarios (T1059) con privilegios elevados (T1548).

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.
