Privilege escalation on an isolated system

[Brahim Sakka <brahim.sakka () gmail com>]

Hello list,

I have a Windows XP SP3 test system with a limited user account. I
want to escalate my privileges and "getsystem".
Typically, I would generate an evil file with MSF, get a meterpreter
shell then getsystem. However, in this particular case, the system
cannot be connected to any network (no NICs). Also, I can't install
MSF itself on it because I don't have the required privileges.

Is it somehow possible to leverage the framework's built-in privilege
escalation capabilities in order to get admin priveleges?
