# CVE-2025-7503

> 10.0 CRITICAL · 🧪 PoC

## Beschreibung

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.
