The Java Database Connectivity (JDBC) classes of Microsoft’s Java virtual machine (VM) do not properly validate DLL requests, allowing a malicious applet to load and execute any DLL on the client system.
Microsoft’s Java VM is installed on Windows 98, NT, 2000, and XP. It is used by Internet Explorer and Outlook Express to execute Java applets.
The VM includes classes that provide JDBC functionality to Java applets. These classes do not properly validate requests to load and execute a DLL on the client system. Such requests are only to be honored if they come from applets that are authorized to load and execute DLLs. However, an unauthorized applet can send a request malformed in such a way that it will be accepted and honored by the JDBC classes. This vulnerability allows malicious Java applets to load and execute any DLL on the client system.
A malicious Java applet can load and execute any DLL on the client system.
