DescriptionCVE.org

GeoVision GV-LPC2211 V1.13 fails to limit repeated User elements in ONVIF CreateUsers requests, allowing an authenticated administrator to overwrite stack control state and crash the ONVIF worker.

AnalysisAI

Stack-based buffer overflow in the GeoVision GV-LPC2011/LPC2211 V1.13 ONVIF CreateUsers handler allows an authenticated administrator to crash the ONVIF worker process by submitting a crafted SOAP request containing repeated User XML elements. The vulnerability overwrites stack control state, resulting in a denial-of-service condition limited to the ONVIF subsystem. …
