I think this is an old bug in the Cisco DSL routers, and not really directly
related to the "code red" worm.  If the router runs an old version of
CBOS, justissuing GET ? will lock it up.  Like you mentioned, the best thing would
be todisable the web interface or upgrade the firmware.

Take a look at Bugtraq ID 2012 and this post from the archives:

It might be related.
