Metasploit Framework

Following is just a quick railgun script that checks to see if the use you are on as has administrative privs to the current box. I call it amiadmin.rb but it can double as an example on how to load dlls that aren't apart of the base with error checking.

if client.platform == "x64/win32" 
        print_status "Railgun is currently not supported for x64 bit systems" 
        raise Rex::Script::Completed
end

if client.railgun.present? == true
        print_status "Railgun already loaded.. skipping" 
else
        print_status "Loading Railgun" 
        client.core.use("railgun")
end

if client.railgun.dll['shell32'] == nil
        print_status "Adding Shell32.dll" 
        client.railgun.add_dll('shell32','shell32')
else
        print_status "Shell32 already loaded.. skipping" 
end

if (client.railgun.shell32.respond_to? :IsUserAnAdmin)  == true
        print_status "IsUserAnAdmin already loaded.. skipping" 
else
        print_status "Adding the IsUserAnAdmin function" 
        client.railgun.add_function('shell32', 'IsUserAnAdmin', 'BOOL', [])
end

print_status "Running the IsUserAnAdmin function" 
status = client.railgun.shell32.IsUserAnAdmin()

if status["return"] == true then
        print_status "You are an administrator" 
        print_error status.inspect
else
        print_error "You are not an administrator" 
end
