This module exploits a vulnerability caused due to an error in the MPC::HTML::UrlUnescapeW() function in helpctr.exe when escaping URLs. This module runs a web server waiting for vulnerable clients (Internet Explorer) to connect to it. When the client connects, it will try to install an agent by exploiting this vulnerability.
This module exploits a vulnerability in Visual Basic 6 .vbp files. The vulnerability is caused due to boundary error in VB6.EXE within the processing of VBP archives. This can be exploited to cause a stack-based buffer overflow when a specially crafted file is opened. This module runs a malicious web site on the Core Impact Console and waits for an unsuspecting user to trigger the exploit by connecting to the web site.
