Description

This module injects a malformed UDP packet to crash Wireshark and TShark 1.8.0 to 1.8.7, as well as 1.6.0 to 1.6.15. The vulnerability exists in the CAPWAP dissector which fails to handle a packet correctly when an incorrect length is given.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/dos/wireshark/capwap
msf auxiliary(capwap) > show actions
    ...actions...
msf auxiliary(capwap) > set ACTION < action-name >
msf auxiliary(capwap) > show options
    ...show and set options...
msf auxiliary(capwap) > 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.
