## Technical details

The vulnerability is a stack buffer overflow in the ONVIF DeleteUsers request handler. The vulnerable component fails to validate or limit the number of repeated Username XML elements in incoming DeleteUsers requests. An authenticated administrator can exploit this by sending a request with an excessive number of Username elements, causing a stack array to overflow and crash the ONVIF worker process. No patches have been publicly announced at the time of advisory publication. The attack requires valid administrator credentials and network reachability to the ONVIF service port.
