Zyxel P660 series modem/router denial of service vulnerability
Zyxel P660 series modem/router contains a denial of service vulnerability when parsing a high volume of SYN packets on the web management interface.
It has been reported that Zyxel P660 series modem/router (and possibly other models which share the same core firmware) fail to parse a high volume of SYN packets on the web management interface correctly causing the device to reboot. By default, the device runs a web management interface on port tcp/80 which is accessible remotely (LAN and WAN sides).
An unauthenticated attacker can cause the device to reboot and become unavailable by sending a stream of SYN packets to the device's web management interface.
We are currently unaware of a practical solution to this problem.
