受影响系统：
Microsoft Visual Studio 6.0描述：
BUGTRAQ ID: 25638
Microsoft Visual Studio是微软公司的开发工具套件系列产品，是一个基本完整的开发工具集，包括了软件整个生命周期中所需要的大部分工具。
Visual Studio所安装的PDWizard.ocx ActiveX控件没有正确地验证对StartProcess()、SyncShell()、SaveAs()、CABDefaultURL()、CABFileName()、CABRunFile()等方式的输入参数，如果用户受骗访问了恶意网页并向这些方式传送了超长参数的话，就可能导致执行任意指令，控制受影响的系统。

<b>Description:
This ocx contains a lot of extreme dangerous methods. Theese two are very interesting, they are:
"StartProcess()" and "SyncShell()"
Using one of them, you'll be able to run every program you like, simply giving to the method the
right argument.
In this PoC, I use the "StartProcess()" method to execute the calc.exe, but you can do everything
you like.
Anyway, I think you could imagine what impact could have this kind of vulnerability :D
Other dangerous methods of this ocx are:
"SaveAs()"
"CABDefaultURL()"
"CABFileName()"
"CABRunFile()"</b>
