CVE-2019-25729

Estado: AplazadaCrítica (9.3)—

PDF Signer 3.0 contains a server-side template injection vulnerability that allows unauthenticated attackers to execute arbitrary code by injecting PHP commands through the CSRF-TOKEN cookie parameter. Attackers can craft malicious cookie values containing template injection payloads like shell_exec() to execute system commands and retrieve sensitive information from the server.

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.

Vulnerabilidad remota sin autenticación (AV:N/PR:N/UI:N) en aplicación web expuesta; SSTI permite ejecución de comandos PHP (shell_exec) y acceso a información sensible del servidor.

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.
