List of CVEs: CVE-2020-0796
This module is also known as SMBGhost or CoronaBlue.
A vulnerability exists within the Microsoft Server Message Block 3.1.1 (SMBv3) protocol that can be leveraged to execute code on a vulnerable server. This local exploit implementation leverages this flaw to elevate itself before injecting a payload into winlogon.exe.
Module Ranking and Traits
Module Ranking:
- good: The exploit has a default target and it is the "common case" for this type of software (English, Windows 7 for a desktop app, 2012 for server, etc). 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-os-restarts: Module may crash the OS, but the OS restarts.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
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
A vulnerability exists within the Microsoft Server Message Block 3.1.1 (SMBv3) protocol that can be leveraged to execute code on a vulnerable server. This local exploit implementation leverages this flaw to elevate itself before injecting a payload into winlogon.exe.
This vulnerability was patched in March 2020 but prior to that enough information was publicly available to trigger a crash which led to pre-patch workarounds. The official recommendation from Microsoft at the time was to disable SMBv3 compression, a feature which this exploit relies on. The module's check method will determine this value using the registry to identify whether or not compression has been disabled.
Other recommendations included restricting access to TCP port 445 via firewalls. Given that this is a local exploit and the connection is made to the local host this is likely an ineffective measure against this particular implementation of the vulnerability.
Installation And Setup
Windows 10 versions 1903 and 1909 (without the patch) are vulnerable out of the box. The default setting is to have SMBv3 compression enabled.
Verification Steps
- Start msfconsole
- Get a Meterpreter session on a vulnerable host
- Do:
use exploit/windows/local/cve_2020_0796_smbghost
- Set the
SESSION
andPAYLOAD
options - Do:
run
- You should get a shell.
