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。只要讲addslashes()改为mysql_real_escape_string()即可。

打开/include/dedevote.class.php文件,查 找$this->dsql->ExecuteNoneQuery("UPDATE `#@__vote` SET totalcount='".($this->VoteInfos['totalcount']+1)."',votenote='".addslashes($items)."' WHERE aid='".$this->VoteID."'");

修改为

$this->dsql->ExecuteNoneQuery("UPDATE `#@__vote` SET totalcount='".($this->VoteInfos['totalcount']+1)."',votenote='".mysql_real_escape_string($items)."' WHERE aid='".mysql_real_escape_string($this->VoteID)."'");

注:

* addslashes() 是强行加\;

* 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)

* 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)
