Hello, I found what I think is an undocumented bug of at least the cisco 760 series, I tried to report it to cisco but they are always busy and english is one of my weak points. The bug: When you open about 98 connections to the port 23 of a Cisco 760 router it does a self reboot disconnecting it ,obviously, from the net, if you keep opening connections it results on a denial of service, I don't know if arbitrary code execution is possible at any point of the process. I've also written an exploit in C++, it has been tested on Redhat 6.0 and FreeBSD 4.0 and it works allright. Thanks <HR NOSHADE> <UL> <LI>text/plain attachment: cisco.c </UL>
