SQL injection is caused by loose filtering of parameters ## Vulnerability impact version - < v1.8.7 ## Vulnerability analysis The vulnerability appears in the core framework of the rockoa,and all routes based on this framework will be affected. Problems in the general processing framework`webmain/webmainAction.php` `publictreestore` method.  As you can see,the 'where' parameter is actually accepted directly by the post.As we became more familiar with the framework,we found that this type of processing was flawed,with SQL statements defined almost as parameters passed,but it seemed like the url was a normal link. ## Vulnerability review get request ``` http://catfish.demo/?a=publictreestore&m=schedule|system/schedule&ajaxbool=true&tablename_abc=admin&pidfields=id&fistid=1&idfields=tel ``` - Cookies with normal user privileges are required The administrator user information is returned
