'Name' => 'MS10-022 Microsoft Internet Explorer Winhlp32.exe MsgBox Code Execution',
'Description' => %q{
This module exploits a code execution vulnerability that occurs when a user
presses F1 on MessageBox originated from VBscript within a web page. When the
user hits F1, the MessageBox help functionality will attempt to load and use
a HLP file from an SMB or WebDAV (if the WebDAV redirector is enabled) server.
This particular version of the exploit implements a WebDAV server that will
serve HLP file as well as a payload EXE. During testing warnings about the
payload EXE being unsigned were witnessed. A future version of this module
might use other methods that do not create such a warning.
