i have just installed an adsl modem sold under the brand of Zoom X3


and was apalled to find that an nmap scan of the external address
immediately came up with the following:

  23/tcp  open  telnet
  80/tcp  open  http
  254/tcp open  unknown
  255/tcp open  unknown

[ snip ]

Someone please correct me if im wrong but i found reports of this issue that go
back to October 2003 ( http://www.securityfocus.com/bid/8765/ ) from reasearch
i found that the prob is in the Conexant CX82310-14 chipset with firmware

this is a completely different problem. full details here:


however, it seems the open ports problem been known about since at least May as i've now found reference to it here:
