这里有新鲜出炉的精品教程,程序狗速度看过来!

Discuz!社区论坛系统

Crossday Discuz! Board(简称 Discuz!)是北京康盛新创科技有限责任公司推出的一套通用的社区论坛软件系统。自2001年6月面世以来,Discuz!已拥有13年以上的应用历史和200多万网站用户案例,是全球成熟度最高、覆盖率最大的论坛软件系统之一。


本文是一个用python写的针对Discuz7.2版faq.php注入漏洞的一个全自动的注入工具,仅用于广大phper研究学习,请不要用于非法用处.

Discuz 7.2 faq.php全自动利用工具,getshell 以及dump数据,python 版的uc_key getshell部分的代码来自网上(感谢作者)
