you can also find them easly by running a http server version reply. The incorporated web server inside M3 Webramp returns this as version reply <wr_httpd/1.0.24April'9> without the <>. I was aware about this problem for some time and the problem is very dangerous. IF you have more then 1modem attach to it you can simply diconnect the one that is not giving internet juice and make it call yourself and then you have acces to the local net and the internet on their accounts. You can also change the routing table of the device and you can upgrade the firmware easly( or upload a trojan one ). ----- Original Message ----- From: ET LoWNOISE <etat_private> To: <BUGTRAQat_private> Sent: Tuesday, August 03, 1999 11:34 AM Subject: [LoWNOISE] Password hunting with webramp > Hi, > Just to go deeper. > > Definition: (taken from www.webramp.com) > What is a WebRamp? > > A WebRamp is a communications > device that allows your whole office to > share Internet access.
