CVE-2025-34132

Estado: AplazadaCrítica (9.3)—

A command injection vulnerability exists in LILIN Digital Video Recorder (DVR) devices prior to firmware version 2.0b60_20200207 via the Server field in the NTPUpdate configuration. The web service at /z/zbin/dvr_box fails to properly sanitize input, allowing remote attackers to inject and execute arbitrary commands as root by supplying specially crafted XML data to the DVRPOST interface.

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 en servicio web remoto sin autenticación (AV:N/PR:N). Permite ejecución de código arbitrario como root vía parámetro NTP no sanitizado.

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.
