DescriptionCVE.org
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.
Executive ViewAI
Our organization faces critical risk from OEM IP cameras with exposed default credentials enabling unauthorized root-level access. Any camera on our network can be remotely compromised to conduct surveillance, launch lateral attacks, or serve as a pivot point into core systems. Immediate inventory and isolation of affected devices is required to prevent breach.
Network segmentation: isolate camera subnet with no direct access to corporate LAN or critical systems. Firewall rules: block all inbound/outbound Telnet (port 23) traffic from camera devices. Network monitoring: deploy IDS/IPS signatures to alert on port 23 connections and suspicious outbound activity from cameras. Access controls: restrict camera management to dedicated admin VLAN with multi-factor authentication. Disable or power down affected devices pending replacement if business-critical alternative exists.

Attack Technique
Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.
Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
