-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Advisory ID: SYSS-2015-020 Product(s): ZENWorks Mobile Management Vendor: Novell Affected Version(s): 3.1.0 Tested Version(s): 3.1.0 Vulnerability Type: Cross-Site Scripting (CWE-79) Risk Level: Medium Solution Status: Open Vendor Notification: 2015-04-21 Solution Date: Public Disclosure: 2015-06-12 CVE Reference: Not yet assigned Author of Advisory: Ludwig Stage (SySS GmbH) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Overview: ZENWorks Mobile Management is a mobile device management software by Novell supporting different kinds of mobile devices. The vendor Novell describes the product as follows (see [1]): "Novell ZENworks Mobile Management is a product that allows customers to manage and secure the full lifecycle of their mobile device workforce, from one web services console, using similar concepts that ZENworks customers have come to appreciate; ie, users, policies, and mobile apps." ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Vulnerability Details: The SySS GmbH found several reflected cross-site scripting vulnerabilities in the web application component of the Novell ZENWorks Mobile Management solution which can be exploited from different attacker's perspectives. 1) Reflected Cross-Site Scripting in login form The parameters "username" and "domain" are not sanitized sufficiently resulting in a reflected cross-site scripting vulnerability. This reflected cross-site scripting vulnerability can be exploited in the context of an unauthenticated user by sending a specially crafted HTTP POST or HTTP GET request (see PoC section). ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Proof of Concept (PoC): 1.1) Reflected Cross-Site Scripting in login form using HTTP POST The following HTTP POST request using the JavaScript code "onfocus="alert(1) as the value for the parameter "username" demonstrates the reflected cross-site scripting vulnerability by showing a JavaScript alert box: POST /index.php HTTP/1.1 Host: Content-Type: application/x-www-form-urlencoded Content-Length: 29 username="onfocus%3d"alert(1) 1.2) Reflected Cross-Site Scripting in login form using HTTP GET The following HTTP GET requests using the JavaScript code "onfocus="alert(1) as the value for the URL parameter "username" demonstrate the two reflected cross-site scripting vulnerabilities by showing a JavaScript alert box. URL: https:///index.php?username="onfocus="alert(1) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Solution: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Disclosure Timeline: 2015-04-21: Vulnerability reported to vendor 2015-04-29: Reported vulnerability again as the vendor did not reply to to the first e-mail with the SySS security advisory 2015-06-02: Reported vulnerability again as the vendor did not reply to to the second e-mail with the SySS security advisory 2015-06-08: Reported vulnerability again as the vendor did not reply to to the third e-mail with the SySS security advisory 2015-06-12: Public release of security advisory according to the SySS Responsible Disclosure Policy ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ References: [1] Product Web Site for Novell ZENWorks Mobile Management https://www.novell.com/products/zenworks/mobile-management/ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Credits: This security vulnerability was found by Ludwig Stage of the SySS GmbH.
