<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>DedeCMS投票模块有朋友反映投票主题的选项经常被sql注入删除，经过iOS100知识库查看代码发现投票模块代码没有对sql参数进行转换，导致不法分子sql注入。只要将addslashes()改为mysql_real_escape_string()即可。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
打开/include/dedevote.class.php文件，查 找$this->dsql->ExecuteNoneQuery("UPDATE `dede_vote` SET totalcount='".($this->VoteInfos['totalcount']+1)."',votenote='".addslashes($items)."' WHERE aid='".$this->VoteID."'");</p>

* mysql_real_escape_string() 会判断字符集，但是对PHP版本有要求；(PHP 4 >= 4.0.3, PHP 5)</p>

* mysql_escape_string不考虑连接的当前字符集。(PHP 4 >= 4.0.3, PHP 5, 注意：在PHP5.3中已经弃用这种方法，不推荐使用)</p>
