There is a Buffer overflow Vulnerability in the device Search and Discovery feature of Hikvision Access Control Products. If exploited, an attacker on the same local area network (LAN) could cause the device to malfunction by sending specially crafted packets to an unpatched device.

Some access control/intercom products have unauthorized modification of device network configuration vulnerabilities. Attackers can modify device network configuration by sending specific data packets to the vulnerable interface within the same local network.
