近期很多使用阿里云的站长收到了阿里云给出的漏洞消息，漏洞名称如下：
Discuz memcache+ssrf GETSHELL漏洞
这里给大家提供一个简单的修复方案！
首先找到这个文件
source/function/function_core.php
搜索代码：

function output_replace($content) {global $_G;if(defined('IN_MODCP') || defined('IN_ADMINCP')) return $content;if(!empty($_G['setting']['output']['str']['search'])) {if(empty($_G['setting']['domain']['app']['default'])) {$_G['setting']['output']['str']['replace'] = str_replace('{CURHOST}', $_G['siteurl'], $_G['setting']['output']['str']['replace']);}$content = str_replace($_G['setting']['output']['str']['search'], $_G['setting']['output']['str']['replace'], $content);}if(!empty($_G['setting']['output']['preg']['search']) && (empty($_G['setting']['rewriteguest']) || empty($_G['uid']))) {if(empty($_G['setting']['domain']['app']['default'])) {$_G['setting']['output']['preg']['search'] = str_replace('\{CURHOST\}', preg_quote($_G['siteurl'], '/'), $_G['setting']['output']['preg']['search']);$_G['setting']['output']['preg']['replace'] = str_replace('{CURHOST}', $_G['siteurl'], $_G['setting']['output']['preg']['replace']);}foreach($_G['setting']['output']['preg']['search'] as $key => $value) {$content = preg_replace_callback($value, create_function('$matches', 'return '.$_G['setting']['output']['preg']['replace'][$key].';'), $content);}}return $content;}

添加一行代码，如下

function output_replace($content) {global $_G;if(defined('IN_MODCP') || defined('IN_ADMINCP')) return $content;if(!empty($_G['setting']['output']['str']['search'])) {if(empty($_G['setting']['domain']['app']['default'])) {$_G['setting']['output']['str']['replace'] = str_replace('{CURHOST}', $_G['siteurl'], $_G['setting']['output']['str']['replace']);}$content = str_replace($_G['setting']['output']['str']['search'], $_G['setting']['output']['str']['replace'], $content);}if(!empty($_G['setting']['output']['preg']['search']) && (empty($_G['setting']['rewriteguest']) || empty($_G['uid']))) {if(empty($_G['setting']['domain']['app']['default'])) {$_G['setting']['output']['preg']['search'] = str_replace('\{CURHOST\}', preg_quote($_G['siteurl'], '/'), $_G['setting']['output']['preg']['search']);$_G['setting']['output']['preg']['replace'] = str_replace('{CURHOST}', $_G['siteurl'], $_G['setting']['output']['preg']['replace']);}if (preg_match("(/|#|\+|%).*(/|#|\+|%)e", $_G['setting']['output']['preg']['search']) !== FALSE) { die("request error"); }//本行代码为新增代码foreach($_G['setting']['output']['preg']['search'] as $key => $value) {$content = preg_replace_callback($value, create_function('$matches', 'return '.$_G['setting']['output']['preg']['replace'][$key].';'), $content);}}return $content;}

然后将修改好的文件保存，上传到服务器目录覆盖一下，然后去阿里云对应漏洞提示后面点击“验证一下”，验证时候漏洞提示就会消失！
问题解决！
