This is a known cisco bug. Their documentation on the bug says something like 'port scanning tools can create a situation where the router CPU utilization goes to 100%'. I don't recall if there is an IOS upgrade to fix this, so call Cisco and ask or go look through their online documentation to see if you IOS is possibly affected.
Please note that I'm replying as a pen-tester who uses nmap and not as Cisco spokesman. I believe the Cisco bug mentioned is the one documented in an advisory released this past May titled "IOS Reload after Scanning Vulnerability." The bug affects devices running IOS version 12.1(1.3)T through IOS releases 12.1(2)T and 12.1(3)T. The complete advisory can be found at http://www.cisco.com/warp/public/707/ios-tcp-scanner-reload-pub.shtml I hope this helps. -- William ---------------------------------------------------------------------------- This list is provided by the SecurityFocus Security Intelligence Alert (SIA) Service.
