Description

This module exploits a buffer overflow in the zhttpd binary (/bin/zhttpd). It is present on more than 40 Zyxel routers and CPE devices.
The code execution vulnerability can only be exploited by an attacker if the zhttp webserver is reachable.
No authentication is required. After exploitation, an attacker will be able to execute any command
as root, including downloading and executing a binary from another host.
