List of CVEs: CVE-2020-13166
This module exploits a ViewState .NET deserialization vulnerability in web-based MS SQL Server management tool myLittleAdmin, for version 3.8 and likely older versions, due to hardcoded <machineKey> parameters in the web.config file for ASP.NET. Popular web hosting control panel Plesk offers myLittleAdmin as an optional component that is selected automatically during "full" installation. This exploit caters to the Plesk target, though it should work fine against a standalone myLittleAdmin setup. Successful exploitation results in code execution as the user running myLittleAdmin, which is IUSRPLESK_sqladmin for Plesk and described as the "SQL Admin MSSQL anonymous account." Tested on the latest Plesk Obsidian with optional myLittleAdmin 3.8.
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.
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:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
Basic Usage
msf > use exploit/windows/http/plesk_mylittleadmin_viewstate
msf exploit(plesk_mylittleadmin_viewstate) > exploit
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'

Vulnerable Application
Description
This module exploits a ViewState .NET deserialization vulnerability in
web-based MS SQL Server management tool myLittleAdmin, for version 3.8
and likely older versions, due to hardcoded <machineKey> parameters in
the web.config file for ASP.NET.
Popular web hosting control panel Plesk offers myLittleAdmin as an optional component that is selected automatically during "full" installation. This exploit caters to the Plesk target, though it should work fine against a standalone myLittleAdmin setup.
Successful exploitation results in code execution as the user running
myLittleAdmin, which is IUSRPLESK_sqladmin for Plesk and described as
the "SQL Admin MSSQL anonymous account."
Tested on the latest Plesk Obsidian with optional myLittleAdmin 3.8.
Setup
Follow Plesk's official
instructions,
making sure to select the "Obsidian" release and the Full installation
option. This will get you myLittleAdmin. Alternatively, you may select
the myLittleAdmin component manually.
Verification Steps
Targets
0
This executes a Windows command.
1
This uses a Windows dropper to execute code.
2
This uses a PowerShell stager to execute code.
Options
RPORT
You may need to change RPORT to where myLittleAdmin is running. It is
set to port 8401 by default for Plesk installations.
Scenarios
myLittleAdmin 3.8 on Plesk Obsidian on Windows Server 2016
