微擎微赞系统BUG漏洞解决方法汇总

弄了微擎系统来玩玩,发觉这个系统BUG还不少,阿里云的提醒都一大堆,主要是没有针对SQL注入做预防,处理的办法基本都是用转义函数。

微擎系统BUG漏洞解决方法汇总

 

汇总:

1、

微擎任意文件下载
漏洞文件路径:/framework/function/global.func.php
解决方法:


修复方法:
打开/framework/function/global.func.php文件
搜索
if (strexists($t, 'http://')

找到
if (strexists($t, 'http://') || strexists($t, 'https://') || substr($t, 0, 2) == '//') {
return $src;
}

替换为
if((substr($t, 0, 7) == 'http://')||(substr($t, 0, 8) == 'https://')||(substr($t, 0, 2) == '//')){ return $src; }

搞定

保存文件,上传到服务器,去安骑士上验证一下就过了。

2、

微擎SQL注入漏洞
微擎的/web/source/mc/fans.ctrl.php中,对$_GPC['nickname']未进行SQL转义就带入数据库查询中,导致SQL注入的发生。
解决方法:

漏洞在web/source/mc/fans.ctrl.php,修复方法(代码在148行左右)

搜索

$nickname = trim($_GPC['nickname']);

修改为

$nickname = addslashes(trim($_GPC['nickname']));

3、

微擎文件编辑SQL注入
微擎的/web/source/site/article.ctrl.php中对$_GPC['template']、$_GPC['title']、$_GPC['description']、$_GPC['source']、$_GPC['author']参数未进行正确转义过滤,导致SQL注入的产生。
解决方法:

搜索代码 message(‘标题不能为空,请输入标题!‘); 如下图:

微擎系统BUG漏洞解决方法汇总

在 82 行 前添加代码

mysql_set_charset("gbk");
$_GPC[‘template‘] = mysql_real_escape_string($_GPC[‘template‘]);
$_GPC[‘title‘] = mysql_real_escape_string($_GPC[‘title‘]);
$_GPC[‘description‘] = mysql_real_escape_string($_GPC[‘description‘]);
$_GPC[‘source‘] = mysql_real_escape_string($_GPC[‘source‘]);
$_GPC[‘author‘] = mysql_real_escape_string($_GPC[‘author‘]);

修改后如图:

4、
微擎SQL注入漏洞
微擎CMS的/web/source/paycenter/wxmicro.ctrl.php中,对$post['member']['uid']输入参数未进行严格类型转义,导致SQL注入的发生
解决方法:

6、
微擎最新版SQL注入
htmlspecialchars_decode 函数对全局过滤gpc产生的 \’ 进行转义,将可控的参数$html的污染值插入数据库后,产生SQL注入漏洞
位置:/web/source/site/editor.ctrl.php
解决方法:
打开“/web/source/site/editor.ctrl.php”文件,从第127行找到“if (!empty($nav)) {”然后在下面加上“$nav['id'] = intval($nav['id']);”保存文件去验证一下就OK了。
