ms-foxpro-app-execution (10035) The risk level is classified as MediumMedium Risk


Visual FoxPro could allow a remote attacker to execute a Visual FoxPro application on another user's system. This vulnerability is caused by Visual FoxPro's failure to register itself with Internet Explorer during installation. A remote attacker could exploit this vulnerability by creating a malicious Web page that would call a known Visual FoxPro application using a specially-crafted application name. Once a victim views the malicious Web page either by visiting a Web site or as an HTML email, the specified FoxPro application would be executed, which could allow the attacker to perform any action on the system with the same privileges as the victim.
