## Technical details

This vulnerability is a stack buffer overflow in the ONVIF CreateUsers request handler. The vulnerable component fails to properly validate and limit the number of repeated User elements in the request, allowing an attacker to write beyond allocated buffer boundaries. The attack requires authentication as an administrator on the device and network access to the ONVIF service port. Successful exploitation causes the ONVIF worker process to crash, resulting in denial of service of ONVIF-based management and user creation functions. A patch is expected in a future firmware release.
