This module exploits a vulnerability in the Microsoft Kerberos implementation. The problem exists in the verification of the Privilege Attribute Certificate (PAC) from a Kerberos TGS request, where a domain user may forge a PAC with arbitrary privileges, including Domain Administrator. This module requests a TGT ticket with a forged PAC and exports it to a MIT Kerberos Credential Cache file. It can be loaded on Windows systems with the Mimikatz help. It has been tested successfully on Windows 2008.
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/kerberos/ms14_068_kerberos_checksum
msf auxiliary(ms14_068_kerberos_checksum) > show actions
...actions...
msf auxiliary(ms14_068_kerberos_checksum) > set ACTION < action-name >
msf auxiliary(ms14_068_kerberos_checksum) > show options
...show and set options...
msf auxiliary(ms14_068_kerberos_checksum) > 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.
