Module Overview
Name: Windows Escalate UAC Protection Bypass (Via Shell Open Registry Key)
Module: exploit/windows/local/bypassuac_sdclt
Source code: modules/exploits/windows/local/bypassuac_sdclt.rb
Disclosure date: 2017-03-17
Last modification time: 2021-10-06 13:43:31 +0000
Supported architecture(s): -
Supported platform(s): Windows
Target service / protocol: -
Target network port(s): -
List of CVEs: -
This module will bypass Windows UAC by hijacking a special key in the Registry under the current user hive, and inserting a custom command that will get invoked when Window backup and restore is launched. It will spawn a second shell that has the UAC flag turned off. This module modifies a registry key, but cleans up the key once the payload has been invoked.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Side Effects:
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
- screen-effects: Module may show something on the screen (Example: a window pops up).
Basic Usage
Note: To run a local exploit, make sure you are at the msf prompt.
Also, to check the session ID, use the sessions command.

msf exploit(bypassuac_sdclt) > set SESSION session-id
msf exploit(bypassuac_sdclt) > exploit
Required Options
- SESSION: The session to run this module on.
Knowledge Base
Introduction
This module exploits an autoelevate feature in the windows backup system's sdclt.exe binary to run as a higher integrity process.
Usage
- Create a session on the target system under the context of a local administrative user.
- Begin interacting with the module:
use exploit/windows/local/bypassuac_sdclt. - Set the
PAYLOADand configure it correctly. - If an existing handler is configured to receive the elevated session, then the module's
handler should be disabled:
set DisablePayloadHandler true. - Make sure that the
SESSIONvalue is set to the existing session identifier. - Invoke the module:
run.
