HTTP: Cisco Scanner Probe

This signature detects connections by the "Cisco Scanner" exploitation tool that searches for Cisco routers' HTTP administration interfaces and attempts to exploit them. Numerous vulnerabilities in the HTTP interface allow remote attackers complete control of the router.

Extended Description

IOS is router firmware developed and distributed by Cisco Systems. IOS functions on numerous Cisco devices, including routers and switches. It is possible to gain full remote administrative access on devices using affected releases of IOS. By using a URL of http://router.address/level/$NUMBER/exec/.... where $NUMBER is an integer between 16 and 99, it is possible for a remote user to gain full administrative access. This problem makes it possible for a remote user to gain full administrative privileges, which may lead to further compromise of the network or result in a denial of service.
