|
||||||
|
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.
