Microsoft Virtual Machine (VM) JDBC classes can execute local DLLs

msvm-jdbc-dll-execution (10133) The risk level is classified as HighHigh Risk


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.
