Brief description:

Http://uyan.cc is the newly established community comment entrepreneurial company, its SQL filter lax caused by vulnerabilities.

Detailed description:

The http://uyan.cc/index.php/youyan_content/getRepliesTogether/time does not filter the post data. Simultaneously http://uyan.cc/index.php/youyan? Title = % E5 % 9B % BD % E5 % 86% E4 % BA % E5 % 852% 9B % E4 % B8 % leaked the file path.
