LinkSys WRT54G administration page availble to WAN

Manufacturer: LinkSys (a division of Cisco)
Product: Wireless-G Broadband Router
Model: WRT54G
Product Page:
Firmware tested: v2.02.7

In a recent client installation I discovered that even if the remote
administration function is turned off, the WRT54G provides the
administration web page to ports 80 and 443 on the WAN.  The implications
are obvious: out of the box the unit gives full access to its administration
from the WAN using the default or, if the user even bothered to change it,
an easily guessed password.

I reported this to LinkSys (along with a number of other non-security
related issues) on April 28.  I received no reponse addressing this, and no
updated firmware has yet appeared on their firmware page

To work around this, you can use the port forwarding (irritatingly renamed
to Games and whatever) to send ports 80 and 443 to non-existant hosts.  Note
that forwarding the ports to any hosts -- inluding listening ones if you are
actually running servers -- will override the default behavior.

On a personal note, there are a number of reasons for which I am thoroughly
disappointed with LinkSys since the acquisition by Cisco.  For the sake of
what was once a rock-solid product and great brand name, I hope things
change soon.
