Some access control products are vulnerable to a session hijacking attack because the product does not update the session ID after a user successfully logs in. To exploit the vulnerability, attackers have to request the session ID at the same time as a valid user logs in, and gain device operation permissions by forging the IP and session ID of an authenticated user.

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.
