CVE-2025-34130

Estado: AplazadaAlta (8.7)—

An unauthenticated arbitrary file read exists in LILIN Digital Video Recorder (DVR) devices prior to firmware version 2.0b60_20200207 via the /z/zbin/net_html.cgi endpoint. This vulnerability allows attackers to read sensitive configuration files, such as /zconf/service.xml, which can then be used to facilitate further attacks including command injection. The vulnerability has been exploited in the wild in conjunction with other issues by botnets like FBot and Moobot.

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.

Acceso remoto sin autenticación (PR:N, UI:N) a endpoint expuesto /z/zbin/net_html.cgi permite lectura arbitraria de ficheros (CWE-200). Archivos de configuración sensibles como service.xml exponen credenciales para escalada posterior.

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.
