采用windbg 调试xp。
执行cmd。whoami检查权限如下面：
以下要做的就是把cmd.exe 的token值用system的token替换。
1、 Ctrl + break ,windbg进入调试模式
。process 0 0 查看xp全部进程，结果例如以下：
kd> !process 0 0
**** NT ACTIVE PROCESS DUMP ****

可知Token的偏移位于eprocess的c8偏移处。查看cmd.exe的eprocess得token例如以下:
kd> dd 8623bc10+c8 8623bcd8 e1653d4d 00000001 ee4edca0 00000000 8623bce8 00040001 00000000 8623bcf0 8623bcf0 8623bcf8 00000000 0001f55b 00000001 ee4edca0 8623bd08 00000000 00040001 00000000 8623bd14 8623bd18 8623bd14 00000000 00000000 00000000 8623bd28 00000000 8605bbe8 86484fd8 00000000 8623bd38 0000009a 00000000 e18da658 00000000 8623bd48 e1f33840 4ad00000 85feab08 00000000

4、 将cmd的token值用system的token值替换
kd> ed 8623bcd8 e10017cd kd> dd 8623bc10+c8 8623bcd8 e10017cd 00000001 ee4edca0 00000000 8623bce8 00040001 00000000 8623bcf0 8623bcf0 8623bcf8 00000000 0001f55b 00000001 ee4edca0 8623bd08 00000000 00040001 00000000 8623bd14 8623bd18 8623bd14 00000000 00000000 00000000 8623bd28 00000000 8605bbe8 86484fd8 00000000 8623bd38 0000009a 00000000 e18da658 00000000 8623bd48 e1f33840 4ad00000 85feab08 00000000
5、 查看cmd进程的token
kd> !process 0 1 cmd.exe

可见，改动后cmd.exe进程的token 值和system进程的Token值同样，在cmd.exe进程測试whoami查看结果：
此时cmd.exe执行whoami它已成为ntsystem才干
