Who is Vulnerable?
Vulnerability Description Microsoft Visual FoxPro 6.0 is designed for building data-centric Windows applications. Visual FoxPro 6.0 is shipped with a set of various ActiveX controls that are registered on the host upon installation. Specifically, an ActiveX control vfp6r.dll is included. There exists an access control weakness vulnerability in the way Microsoft Visual FoxPro ActiveX Control handles user supplied data. The vulnerability is a result of insufficient data validation while processing a method call from a webpage script. A remote attacker can exploit this vulnerability by enticing the target user to open a malicious webpage, potentially allowing arbitrary code to be executed in the security context of the currently logged-in user. An attack targeting this vulnerability can result in arbitrary command execution. If command execution is successful, the behaviour of the target will depend on the intention of the attacker. Any command will be executed within the security context of the currently logged in user. Note that after the command execution, Internet Explorer is likely to become unresponsive. Restoration of the functionality of Internet Explorer might need manual termination of the process.
