"HD Moore is at it again. Using a custom-built data fuzzing tool, the security researcher pinpointed more than 100 vulnerabilities in the ActiveX controls included with the default installation of Microsoft's Windows XP operating system. Data fuzzing tools combine knowledge of the input parameters accepted by a software package with a tenacious and systematic mangling of the data to discover how applications react to various permutations, whether valid or invalid. Moore claims that, while he found more than 100 vulnerabilities in standard ActiveX components, almost another 100 exist in the ActiveX components installed by popular applications, such as Microsoft Office. While most of the issues discovered by Moore, who is also the founder of the Metasploit Project, are simple denial-of-service problems, about a dozen are remotely exploitable issues in ActiveX controls for Internet Explorer, he said. "There are a couple of classes that have so many vulnerabilities that I had to black list the entire class," Moore said. The research underscores the security problems posed by ActiveX controls. ActiveX allows Web sites to add interactivity and greater functionality to visitor's browsing experience. However, because the technology allows Web site to affect changes on a visitor's PCs, the technology also poses a danger. Online criminals frequently use flaws in ActiveX to install malicious code on victim's browsers… To minimize the danger of attack in the future, Microsoft plans to disable by default all but the most commonly used ActiveX controls in its coming browser, Internet Explorer 7. Moreover, the company will also use more informative warnings to users before allowing them to install new ActiveX controls, a feature the software giant calls ActiveX Opt-in…"
