Features

Checks SNMP is enabled on the route
Brute forces the SNMP Read Only and Read Write community strings (can edit which wordlist it uses in script header)
Enumerates information such as IOS version, hostname, Arp table, Routing table, interface list and IP addresses using the RO or RW community string.
If RW community was found it will then download the router config automatically.
It then searches and displays any enable or telnet passwords in clear text.
If it finds Cisco type 7 encoded enable or telnet passwords it will auto decode them.
It will display the Enable secret type 5 password and attempt to crack the MD5. It uses John first with its built in wordlist for speed. If this fails it will try and full crack.
