Puwell IP Camera firmware versions 2.x through 4.x contains an authentication bypass vulnerability that allows unauthenticated attackers to access device functions by sending protocol-conforming packets over TCP port 23456 without credentials. Attackers can exploit the unvalidated Session field in the proprietary control protocol header to access live video streams, control pan and tilt motors, activate audio functions, and remotely restart the device.
