Summary

The ZyXEL ZyWALL 10 firewall prior to version 3.50 is susceptible to a denial of service attack when it receives a specially crafted ARP packet containing its own IP address and an incorrect MAC address. This malicious input can lead to the firewall disabling its LAN interface, effectively disrupting network connectivity for users reliant on the device. Ensuring that firmware is updated to the latest version is essential for maintaining the integrity and availability of network services.
