BlackBerry Enterprise Server Input Validation Bugs Let Remote Users Conduct Cross-Site Scripting and SQL Injection Attacks
SecurityTracker Alert ID:  1035095
SecurityTracker URL:  http://securitytracker.com/id/1035095
CVE Reference:   CVE-2016-1914, CVE-2016-1915   (Links to External Site)
Date:  Feb 24 2016
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 12.3.1 and prior
Description:   Two vulnerabilities were reported in BlackBerry Enterprise Server. A remote user can inject SQL commands. A remote user can conduct cross-site scripting attacks.

The software does not properly validate user-supplied input. A remote user can supply a specially crafted parameter value to execute SQL commands on the underlying database [CVE-2016-1914].

The software does not properly filter HTML code from user-supplied input before displaying the input [CVE-2016-1915]. A remote user can create a specially crafted URL that, when loaded by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the BlackBerry Enterprise Server software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

BlackBerry Enterprise Server (BES) 5 and BES10 are not affected.

Impact:   A remote user can execute SQL commands on the underlying database.

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the BlackBerry Enterprise Server software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Solution:   The vendor has issued a fix (12.4).

The vendor's advisory is available at:
