CVE-2026-85672

Estado: AplazadaCrítica (9.3)—

zerox 1.1.20 contains an OS command injection vulnerability in the file download mechanism where the temporary file extension derived from document URLs is interpolated unsanitized into shell commands executed by poppler utilities. Attackers can craft document URLs with malicious file extensions containing command substitution syntax to execute arbitrary OS commands before document processing occurs.

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 de inyección de comandos OS (CWE-78) en mecanismo de descarga remoto sin autenticación (AV:N, PR:N, UI:N). El atacante manipula extensiones de archivo en URLs de documentos para ejecutar comandos arbitrarios en el servidor a través de poppler.

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.
