Microsoft Virtual Machine (VM) JDBC classes can execute local DLLs
| msvm-jdbc-dll-execution (10133) |  High Risk |
Description:
Microsoft Virtual Machine (VM) could allow a remote attacker to load and execute a local Dynamic Link Library (DLL), caused by a vulnerability regarding the handling of specially-crafted requests by the Java Database Connectivity (JDBC) classes. A remote attacker could create a malicious Java Applet that would call the vulnerable JDBC function that handles DLL requests, and use it to load and execute any DLL on a victim's system. This could allow the attacker to potentially gain complete control over the victim's system, depending on the functionality of the DLL that is being executed. 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Note: Microsoft originally provided a patch for this vulnerability in MS02-052, but it was superseded by the patch released with MS02-069, which was superseded by the patch released with MS03-011.
