Cisco Scanner

Vulnerability Assesstment -> Network Assessment -> Cisco Tools -> cisco passwd scanner

The only item this tool does is scanning a subnet for Cisco devices - it will try to telnet to each IP, and login with the default password "cisco", if this is successful, then it considers to find a device. It's important to mention, that it will basically check the telnet password, which is set on the vty lines, and not the enable password:

router(config)#line vty 0 4
router(config-line)#password cisco

If we change this password, then it won't find the device, so change it. Also never use default passwords.

Example:

./ciscos 192.168.80 3

This will scan the 192.168.80.0/24 subnet (3 means that this we provided a class C subnet).
