Microsoft Virtual Machine (VM) XML methods can be accessed
| msvm-xml-methods-access (10135) |  High Risk |
Description:
Microsoft Virtual Machine (VM) could allow a remote attacker to gain unauthorized access to Extensible Markup Language (XML) support class methods using malicious Java applets. A remote attacker could create a malicious Java Applet that would call the XML support class and use it to pass user-supplied data to any function that the XML support class uses, some of which should only be accessible by trusted programs. This could allow the attacker to potentially gain complete control over the victim's system, depending on which function the data is being passed to. An attacker could exploit this vulnerability by hosting the malicious Java Applet on a Web site or by sending it to a potential victim within an HTML email.
Consequences:
Gain Access
Remedy:
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS03-011. See References.
To determine the build number installed on your system, follow the steps listed in Microsoft Security Bulletin MS02-069 FAQ.
Note: Microsoft originally provided a patch for this vulnerability in MS02-052, but it was superseded by the patch released with MS02-069, which was superseded by the patch released with MS03-011.
