An unauthenticated remote attacker can exploit an authentication flaw in the CP-Plus EZ-P21 IP Camera to gain unauthorized access to sensitive device functionality.

The device fails to properly restrict authentication attempts, allowing for potential bypass or brute-force scenarios on HTTP endpoints. The vulnerability is exploitable by an unauthenticated remote attacker.

The CVSS score of 8.7 highlights the severe risk posed by this vulnerability, as it allows unauthorized access to camera control functions or video streams. This could lead to total loss of privacy, unauthorized surveillance, or the integration of the device into a botnet for further attacks on the internal network.

Immediate Action: Upgrade the firmware of the CP-Plus EZ-P21 IP Camera to version 4.8.16.1 or later via the over-the-air (OTA) update mechanism.

Proactive Monitoring: Review device access logs for unusual patterns of failed login attempts or unauthorized connection requests from unknown IP addresses.

Compensating Controls: Isolate IP cameras on a dedicated VLAN with no direct internet exposure and utilize a firewall to restrict access to the device management interface.

Public Exploit Available: false

Immediate firmware updates are required to secure these devices. If an OTA update is not immediately feasible, the devices must be removed from public-facing network segments to prevent exploitation of the authentication mechanism.
