### 简要描述： 之前也有人爆wps的sql注入，其实wps用的是这个系统 ### 详细说明： 在control/question.php 的onajaxsearch函数中 ``` function onajaxsearch() { $title = urldecode($this-> get[2]); $questionlist = $_ENV[ 'question']->search_title($title, 2, 1, 0, 5); include template('ajaxsearch' ); } ``` 由get[2]传入的参数经过了urldecode再进入到question模块中的search_title函数里。 ``` //根据标题搜索问题 function search_title ($title, $status='1,2,6' , $addbestanswer=0, $start=0, $limit=20) { $questionlist = array(); $search_words = $this->get_words($title); $sql = $search_words ? "SELECT * FROM " . DB_TABLEPRE . "question WHERE MATCH(search_words) AGAINST(' $search_words') AND status IN($status)" : "SELECT * FROM " . DB_TABLEPRE .
