Java AtomicReferenceArray Type Violation Vulnerability

Disclosed

Description

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.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/multi/browser/java_atomicreferencearray
msf exploit(java_atomicreferencearray) > show targets
    ...targets...
msf exploit(java_atomicreferencearray) > set TARGET < target-id >
msf exploit(java_atomicreferencearray) > show options
    ...show and set options...
msf exploit(java_atomicreferencearray) > exploit

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
