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 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.
