CVE-2025-34054

Estado: AplazadaCrítica (10)—

An unauthenticated command injection vulnerability exists in AVTECH DVR devices via Search.cgi?action=cgi_query. The use of wget without input sanitization allows attackers to inject shell commands through the username or queryb64str parameters, executing commands as root. Exploitation evidence was observed by the Shadowserver Foundation on 2025-01-04 UTC.

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 en aplicación expuesta (Search.cgi acceso remoto sin autenticación, AV:N/PR:N) permite inyección de comandos shell (CWE-78) ejecutados como root, logrando ejecución y escalada de privilegios.

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.
