Java is a widely used language for running Windows and other operating system related codes. It is designed in such a way that the applets within it run in a separate “sandbox” environment which helps to prevent them from other application and operating system component access.

But many-a-times, these vulnerabilities allow the applets to escape the sandbox environment and cause threat.
