Vulnerability Detection in ActiveX Controls through Automated Fuzz Testing
• White Paper
Software Engineering Institute
Vulnerabilities in ActiveX controls are frequently used by attackers to compromise systems using the Microsoft Internet Explorer web browser. A programming or design flaw in an ActiveX control can allow arbitrary code execution as the result of viewing a specially-crafted web page. In this paper, we examine effective techniques for fuzz testing ActiveX controls, using the Dranzer tool developed at CERT. By testing a large number of ActiveX controls, we are able to provide some insight into the current state of ActiveX security.
