CVE-2025-7503

Estado: AplazadaCrítica (10)—

An OEM IP camera manufactured by Shenzhen Liandian Communication Technology LTD exposes a Telnet service (port 23) with undocumented, default credentials. The Telnet service is enabled by default and is not disclosed or configurable via the device’s web interface or user manual. An attacker with network access can authenticate using default credentials and gain root-level shell access to the device. The affected firmware version is AppFHE1_V1.0.6.0 (Kernel: KerFHE1_PTZ_WIFI_V3.1.1, Hardware: HwFHE1_WF6_PTZ_WIFI_20201218). No official fix or firmware update is available, and the vendor could not be contacted. This vulnerability allows for remote code execution and privilege escalation.

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/UI:N indica acceso remoto sin privilegios ni interacción. Credenciales por defecto en Telnet expuesto (CWE-798) permite autenticación remota (T1078.001) y acceso shell root (T1059), con capacidad de modificar datos del dispositivo (T1565).

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.
