'Description' => %q{
|
|
This module exploits a vulnerability in PhpMyAdmin's setup
|
|
feature which allows an attacker to inject arbitrary PHP
|
|
code into a configuration file. The original advisory says
|
|
the vulnerability is present in phpMyAdmin versions 2.11.x
|
|
< 2.11.9.5 and 3.x < 3.1.3.1; this module was tested on
|
|
3.0.1.1.
|
|
|
|
The file where our payload is written
|
|
(phpMyAdmin/config/config.inc.php) is not directly used by
|
|
the system, so it may be a good idea to either delete it or
|
|
copy the running config (phpMyAdmin/config.inc.php) over it
|
|
after successful exploitation.
