VULHUB ™

Cisco IOS is the firmware Operating System designed for use on various Cisco hardware. It is maintained by Cisco systems. A problem in IOS makes it possible to cause an arbitrary reload of the operating system. By initiating a TCP scan against a piece of Cisco hardware 3100-3999, 5100-5999, 7100-7999, and 10100-10999, the router becomes unstable and suffers memory corruption. Upon the next attempt to access the configuration, the router will unexpectedly reload the configuration. This problem makes it possible for a remote user to cause an arbitrary reload of the router configuration, and potentially deny service to network assets.
