最近在家做专职奶爸，不谙圈内事很多months了，博客也无更新。
昨夜带孩子整夜未眠，看到黑哥在php security群里关于phpmyadmin3漏洞的讨论，虽然之前没看过漏洞代码，不过前段时间还是在微博上看到wofeiwo的exp了，不过据黑哥说有不鸡肋的利用方法，于是夜里翻代码出来研究了翻，写出了这个冷饭exp，由于我搞的晚了，之前已经很多人研究了写exp了，于是我这个属于炒冷饭，权当研究研究打发时间了。
首先赞下wofeiwo的python版本的exp，再赞下wofeiwo跟superhei的钻研精神，学习的榜样啊。不过之前那个exp利用起来是有一些限制的：
一是session.auto_start = 1；
二是pma3默认代码里libraries目录已经用.htaccess控制了不允许访问。
当然还有第三点大家都不可以逾越的鸿沟：config目录存在且可写。
在群里看了黑哥的发言后，再看了下代码，发现前两点利用限制均可以无视。所以其实这个漏洞还真的可以不是那么鸡肋。
于是写了这个php版本的exp，代码如下：
#!/usr/bin/php
