'Name' => 'Java AtomicReferenceArray Type Violation Vulnerability',

'Description'=> %q{

This module exploits a vulnerability due to the fact that

AtomicReferenceArray uses the Unsafe class to store a reference in an

array directly, which may violate type safety if not used properly.

This allows a way to escape the JRE sandbox, and load additional classes

in order to perform malicious operations.
