List of CVEs: CVE-2020-1170, CVE-2020-17136

The Cloud Filter driver, cldflt.sys, on Windows 10 v1803 and later, prior to the December 2020 updates, did not set the IO_FORCE_ACCESS_CHECK or OBJ_FORCE_ACCESS_CHECK flags when calling FltCreateFileEx() and FltCreateFileEx2() within its HsmpOpCreatePlaceholders() function with attacker controlled input. This meant that files were created with KernelMode permissions, thereby bypassing any security checks that would otherwise prevent a normal user from being able to create files in directories they don't have permissions to create files in. This module abuses this vulnerability to perform a DLL hijacking attack against the Microsoft Storage Spaces SMP service, which grants the attacker code execution as the NETWORK SERVICE user. Users are strongly encouraged to set the PAYLOAD option to one of the Meterpreter payloads, as doing so will allow them to subsequently escalate their new session from NETWORK SERVICE to SYSTEM by using Meterpreter's "getsystem" command to perform RPCSS Named Pipe Impersonation and impersonate the SYSTEM user.

Module Ranking and Traits

Module Ranking:

  • normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.

Reliability:

  • repeatable-session: The module is expected to get a shell every time it runs.

Stability:

  • crash-safe: Module should not crash the service.

Side Effects:

  • artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.

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.

Knowledge Base

Vulnerable Application

The Cloud Filter driver, cldflt.sys, on Windows 10 v1803 and later, prior to the December 2020 updates, did not set the IO_FORCE_ACCESS_CHECK and OBJ_FORCE_ACCESS_CHECK flags when calling FltCreateFileEx() and FltCreateFileEx2() within its HsmpOpCreatePlaceholders() function with attacker controlled input. This meant that files were created with KernelMode permissions, thereby bypassing any security checks that would otherwise prevent a normal user from being able to create files in directories they don't have permissions to create files in.

This module abuses this vulnerability to perform a DLL hijacking attack against the Microsoft Storage Spaces SMP service, which grants the attacker code execution as the NETWORK SERVICE user. Users are strongly encouraged to set the PAYLOAD option to one of the Meterpreter payloads, as doing so will allow them to subsequently escalate their new session from NETWORK SERVICE to SYSTEM by using Meterpreter's getsystem command to perform RPCSS Named Pipe Impersonation and impersonate the SYSTEM user.

Installation And Setup

cldflt.sys should exist by default on all versions of Windows 10 v1803 and later.

Verification Steps

  1. Start msfconsole
  2. Get a shell as a low privileged user.
  3. Verify that getsystem does not get you a SYSTEM shell.
  4. use exploit/windows/local/cve_2020_17136
  5. set session *session id*
  6. run
  7. Verify that you get a new shell as the N user

Options

AMSIBYPASS

Enable or disable ASMI bypass.

ETWBYPASS

Enable or disable ETW bypass.

WAIT

Time in seconds to wait before starting to read the text output from the injected C# exe.
