'Name'=> 'Java Applet Driver Manager Privileged toString() Remote Code Execution',
'Description' => %q{
This module abuses the java.sql.DriverManager class where the toString() method
is called over user supplied classes, from a doPrivileged block. The vulnerability
affects Java version 7u17 and earlier. This exploit bypasses click-to-play on IE
throw a specially crafted JNLP file. This bypass is applied mainly to IE, when Java
Web Start can be launched automatically throw the ActiveX control. Otherwise the
applet is launched without click-to-play bypass.
