Osclass 3.4.2 Local File Inclusion

`--------------------------------------------------------------  
Osclass <= 3.4.2 (ajax.php) Local File Inclusion Vulnerability  
--------------------------------------------------------------  
  
  
[-] Software Link:  
  
http://osclass.org/   
  
  
[-] Affected Versions:  
  
Version 3.4.2 and probably prior versions.  
  
  
[-] Vulnerability Description:  
  
The vulnerable code is located in the /oc-includes/osclass/controller/ajax.php script:  
  
225. case 'custom': // Execute via AJAX custom file  
226. if(Params::existParam('route')) {  
227. $routes = Rewrite::newInstance()->getRoutes();  
228. $rid = Params::getParam('route');  
229. $file = '../';  
230. if(isset($routes[$rid]) && isset($routes[$rid]['file'])) {  
231. $file = $routes[$rid]['file'];  
232. }  
233. } else {  
234. // DEPRECATED: Disclosed path in URL is deprecated, use routes instead  
235. // This will be REMOVED in 3.4  
236. $file = Params::getParam('ajaxfile');  
237. }  
238.   
239. if($file == '') {  
240. echo json_encode(array('error' => 'no action defined'));  
241. break;  
242. }  
243.   
244. // valid file?  
245. if( stripos($file, '../') !== false || stripos($file, '/admin/') !== false ) ...  
246. echo json_encode(array('error' => 'no valid ajaxFile'));  
247. break;  
248. }  
249.   
250. if( !file_exists(osc_plugins_path() . $file) ) {  
251. echo json_encode(array('error' => "ajaxFile doesn't exist"));  
252. break;  
253. }  
254.   
255. require_once osc_plugins_path() . $file;  
  
User input passed through the "ajaxfile" request parameter when handling a "custom" action within  
the AJAX interface is not properly sanitized being used in a call to the "require_once()" function  
at line 255. This can be exploited to include arbitrary local files and execute arbitrary PHP code  
when the application is running on Windows.
