This module implements the DLSw information disclosure retrieval. There is a bug in Cisco's DLSw implementation affecting 12.x and 15.x trains that allows an unauthenticated remote attacker to retrieve the partial contents of packets traversing a Cisco router with DLSw configured and active.
To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':
msf > use auxiliary/scanner/dlsw/dlsw_leak_capture
msf auxiliary(dlsw_leak_capture) > show actions
...actions...
msf auxiliary(dlsw_leak_capture) > set ACTION < action-name >
msf auxiliary(dlsw_leak_capture) > show options
...show and set options...
msf auxiliary(dlsw_leak_capture) > run
Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
