Java AtomicReferenceArray Type Violation Vulnerability - Metasploit
This page contains detailed information about how to use the exploit/multi/browser/java_atomicreferencearray metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.
Module Overview
Name: Java AtomicReferenceArray Type Violation Vulnerability
Module: exploit/multi/browser/java_atomicreferencearray
Source code: modules/exploits/multi/browser/java_atomicreferencearray.rb
Disclosure date: 2012-02-14
Last modification time: 2020-10-02 17:38:06 +0000
Supported architecture(s): -
Supported platform(s): Java, Linux, OSX, Solaris, Windows
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2012-0507
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 Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Basic Usage
msf > use exploit/multi/browser/java_atomicreferencearray

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.
