CVE-2025-34066

Estado: AplazadaAlta (8.3)—

An improper certificate validation vulnerability exists in AVTECH IP cameras, DVRs, and NVRs due to the use of wget with --no-check-certificate in scripts like SyncCloudAccount.sh and SyncPermit.sh. This exposes HTTPS communications to man-in-the-middle (MITM) attacks.

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.

AV:N/PR:N permite explotación remota sin privilegios (T1190). CWE-295 con --no-check-certificate facilita MITM (T1557) para interceptar comunicaciones HTTPS y acceder a datos confidenciales (T1005).

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.
