微擎系统BUG漏洞解决方法汇总（原创）

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。

汇总：

1、

漏洞名称：

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://')
复制代码

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

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

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、

漏洞名称：

微擎SQL注入漏洞

漏洞描述：

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、

漏洞名称：

微擎文件编辑SQL注入

漏洞描述：

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：

在 82 行 前添加代码

1. mysql_set_charset("gbk");
2. $_GPC[‘template‘] = mysql_real_escape_string($_GPC[‘template‘]);
3. $_GPC[‘title‘] = mysql_real_escape_string($_GPC[‘title‘]);
4. $_GPC[‘description‘] = mysql_real_escape_string($_GPC[‘description‘]);
5. $_GPC[‘source‘] = mysql_real_escape_string($_GPC[‘source‘]);
6. $_GPC[‘author‘] = mysql_real_escape_string($_GPC[‘author‘]);

复制代码

修改后如图：

4、

漏洞名称：

微擎SQL注入漏洞

漏洞描述：

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：

红色部分为新增和修改的

漏洞名称：

微擎最新版SQL注入

漏洞描述：

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。
