Date: Tue, 23 Sep 2014 17:12:57 +0200 From: Egidio Romano <research@...mainsecurity.com> To: bugtraq@...urityfocus.com, fulldisclosure@...lists.org Subject: [FD] [KIS-2014-09] X2Engine <= 4.1.7 (SiteController.php) PHP Object Injection Vulnerability ------------------------------------------------------------------------- X2Engine <= 4.1.7 (SiteController.php) PHP Object Injection Vulnerability ------------------------------------------------------------------------- [-] Software Link: http://www.x2engine.com/ [-] Affected Versions: All versions from 2.8 to 4.1.7. [-] Vulnerability Description: The vulnerable code is located in the "actionSendErrorReport" method defined in /protected/controllers/SiteController.php: 153. public function actionSendErrorReport(){ 154. if(isset($_POST['report'])){ 155. $errorReport = $_POST['report']; 156. $errorReport = unserialize(base64_decode($errorReport)); 157. if(isset($_POST['email'])){ 158. $errorReport['email'] = $_POST['email']; 159. } User input passed through the "report" POST parameter is not properly sanitized before being used in a call to the "unserialize()" function at line 156. This can be exploited to inject arbitrary PHP objects into the application scope, and could allow an attacker to carry out Server-Side Request Forgery (SSRF) and possibly other attacks via specially crafted serialized objects. [-] Solution: Apply the vendor patch or update to version 4.2 or later.
