Microsoft Windows is prone to a vulnerability that may allow a file to automatically run because the software fails to handle 'LNK' files properly. Specifically, the issue occurs when loading the icon of a shortcut file. A specially crafted 'LNK' file can cause Windows to automatically execute code that is specified by the shortcut file. The attacker must entice a victim into viewing a specially crafted shortcut. The shortcut file and the associated binary may be delivered to a user through removable drives, over network shares or remote WebDAV shares. An attacker may exploit this issue to execute arbitrary code.
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.
