TrueOnline / ZyXEL P660HN-T v1 Router Unauthenticated Command Injection

Disclosed
Dec 26, 2016

Description

TrueOnline is a major ISP in Thailand, and it distributes a customized version of
the ZyXEL P660HN-T v1 router. This customized version has an unauthenticated command
injection vulnerability in the remote log forwarding page.
This module was tested in an emulated environment, as the author doesn't have access to the
Thai router any more. Any feedback should be sent directly to the module's author, as well as
to the Metasploit project.
There are other language strings in the firmware, so it is likely that this firmware is not only
distributed in Thailand. Other P660HN-T v1 in other countries might be vulnerable too.
