CVE-2026-61514
CriticalCVSS 9.8Summary
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.
Risk Assessment
The risk includes unauthorized access to live video feeds, camera manipulation, and disruption of device operation, which could compromise privacy and physical security.
Recommendation
It is recommended to immediately update the camera firmware to a version newer than 4.x if available, and to restrict access to port 23456 to trusted networks only.
