## Description
|
||||
|
||||
On vulnerable versions of Windows the alpc endpoint method SchRpcSetSecurity implemented by the task scheduler service can be used to write arbitrary DACLs to `.job` files located in `c:\windows\tasks` because the scheduler does not use impersonation when checking this location. Since users can create files in the `c:\windows\tasks` folder, a hardlink can be created to a file the user has read access to. After creating a hardlink, the vulnerability can be triggered to set the DACL on the linked file.
|
||||
|
||||
WARNING:
|
||||
The PrintConfig.dll (%windir%\system32\driverstor\filerepository\prnms003*) on the target host
|
||||
will be overwritten when the exploit runs.
|
||||
|
||||
This module has been tested against Windows 10 Pro x64.
|
||||
|
||||
## Vulnerable Application
|
||||
|
||||
Affected Windows OS versions and related patch details can be found in the [Microsoft Advisory for CVE-2018-8440](https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2018-8440).
|
||||
|
||||
## Verification Steps
|
||||
|
||||
* Get a meterpreter session on Windows 10 x64
|
||||
* `use exploit/windows/local/alpc_taskscheduler`
|
||||
* `set session <session>`
|
||||
* `set payload <payload>`
|
||||
* `set lhost <lhost>`
|
||||
* `run`
|
||||
* Get a session as SYSTEM
|
||||
|
||||
## Scenarios
|
||||
|
||||
### Tested on Windows 10 Pro Version 1803 x64

It will Set the security of a file in c:\windows\tasks without impersonating, a non-admin (works from Guest too) user can write here.

Before the task scheduler writes the DACL we can create a hard link to any file we have read access over.

This will result in an arbitrary DACL write.

This PoC will overwrite a printer related dll and use it as a hijacking vector. This is ofcourse one of many options to abuse this.*/

|
||||
On vulnerable versions of Windows the alpc endpoint method SchRpcSetSecurity implemented
|
||||
by the task scheduler service can be used to write arbitrary DACLs to `.job` files located
|
||||
in `c:\windows\tasks` because the scheduler does not use impersonation when checking this
|
||||
location. Since users can create files in the `c:\windows\tasks` folder, a hardlink can be
|
||||
created to a file the user has read access to. After creating a hardlink, the vulnerability
|
||||
can be triggered to set the DACL on the linked file.
