Description

Broadband DSL modems manufactured by Zyxel and distributed by some European ISPs are vulnerable to a command injection vulnerability when setting the 'NewNTPServer' value using the TR-64 SOAP-based configuration protocol. In the tested case, no authentication is required to set this value on affected DSL modems. This exploit was originally tested on firmware versions up to 2.00(AADU.5)_20150909.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
