OverviewThe JVIEW Profiler COM object contains an unspecified vulnerability, which may allow a remote attacker to execute arbitrary code on a vulnerable system.
I. DescriptionMicrosoft COMMicrosoft COM is a technology that allows programmers to create reusable software components that can be incorporated into applications to extend their functionality. Microsoft COM includes COM+, Distributed COM (DCOM), and ActiveX Controls.
ActiveX controlsActiveX controls are COM objects that are designed to be used in Internet Explorer. A web can make use of an ActiveX control through the use of the OBJECT tag.
JVIEW ProfilerThe JVIEW Profiler is a COM object provided by javaprxy.dll, which is an interface to the debugger in the Microsoft Java Virtual machine.
The ProblemInternet Explorer will attempt to instantiate any COM object that is referenced by a web page. If a COM object is not an ActiveX control, this can cause unexpected results such as crashing Internet Explorer. The JVIEW Profiler COM object crashes in a way that can be exploited to execute arbitrary code on a vulnerable system.
II. ImpactBy convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message), an attacker could execute arbitrary code with the privileges of the user. The attacker could also cause IE (or the program using the WebBrowser control) to crash.
Proof of concept code is publicly available.
III. SolutionWorkarounds
Microsoft has listed several workarounds in the Microsoft Security Advisory, including disabling ActiveX controls, disabling Active scripting, and unregistering javaprxy.dll.
