How To Use

./cisc0wn.sh

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.

Requirements

• Metasploit http://www.metasploit.com
