Summary
A stack-based buffer overflow vulnerability exists in the ssvr component of GeoVision GV-LPC2011 and GV-LPC2211 devices running version V1.12 and earlier. The issue is caused by insufficient bounds checking when processing RTSP custom authentication data. An unauthenticated remote attacker can exploit this vulnerability by sending a crafted RTSP request, potentially leading to memory corruption, denial of service, or arbitrary code execution.
Risk Assessment
The risk for organizations includes the possibility of remote takeover of the vulnerable device, which could result in system integrity compromise, data leakage, or service disruption.
Recommendation
It is recommended to immediately update the firmware of GeoVision GV-LPC2011 and GV-LPC2211 devices to a version later than V1.12. If an update is not available, restrict access to RTSP ports to trusted networks only.
