CVE-2025-30140

Status: AnalyzedHigh (7.5)—

An issue was discovered on G-Net Dashcam BB GONX devices. A Public Domain name is Used for the Internal Domain Name. It uses an unregistered public domain name as an internal domain, creating a security risk. This domain was not owned by GNET originally, allowing an attacker to register it and potentially intercept sensitive device traffic (it has since been registered by the vulnerability discoverer). If the dashcam or related services attempt to resolve this domain over the public Internet instead of locally, it could lead to data exfiltration or man-in-the-middle attacks.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

🎯 ATT&CK techniques

How this vulnerability is exploited and what the attacker gains, in MITRE ATT&CK terms.

Vulnerabilidad de dominio público sin registrar permite a atacante registrarlo e interceptar tráfico del dispositivo (MITM/DNS hijacking). Acceso de red sin autenticación, confidencialidad alta. Exfiltración de datos sensibles del dashcam.

Inferred by our analysis agent from the official description, CVSS vector and CWE, and checked by a supervisor. May contain errors.
