CVE-2015-4112 in BlackBerry
Summary
by MITRE
The Management Console in BlackBerry Enterprise Server (BES) 12 before 12.2 does not properly restrict use of FRAME elements, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web site, related to a "cross frame scripting" issue.

The vulnerability identified as CVE-2015-4112 affects the Management Console component of BlackBerry Enterprise Server version 12.0 through 12.1, representing a critical security flaw that undermines the integrity of web-based administrative interfaces. This issue stems from insufficient restrictions on FRAME element usage within the web console, creating an environment where malicious actors can exploit cross-frame scripting techniques to manipulate user interactions. The vulnerability specifically targets the server's administrative web interface, which is crucial for enterprise security management and configuration.
The technical flaw manifests through improper handling of HTML FRAME elements that allow external web content to be embedded within the management console interface. This lack of proper frame restriction mechanisms enables attackers to construct malicious websites that can overlay legitimate administrative interfaces with deceptive content. When users interact with what appears to be a legitimate administrative interface, they may unknowingly perform actions on the actual backend system through carefully crafted clickjacking attacks. The vulnerability is classified under CWE-1021, which specifically addresses improper restriction of cross-frame scripting, making it a well-documented pattern of web application security weaknesses.
The operational impact of this vulnerability is significant for enterprises relying on BlackBerry Enterprise Server for their mobile device management. Attackers can leverage this weakness to execute unauthorized administrative actions without proper authentication, potentially leading to complete compromise of the mobile device management infrastructure. The attack surface extends beyond simple data theft to include the ability to modify device policies, manage user accounts, and potentially escalate privileges within the enterprise environment. Organizations using BES 12.0 through 12.1 are particularly vulnerable as the flaw affects the core administrative interface that handles sensitive enterprise data and device management operations.
Mitigation strategies for this vulnerability include immediate deployment of the official BlackBerry Enterprise Server 12.2 patch which addresses the frame restriction issue. Organizations should also implement additional defensive measures such as Content Security Policy headers that prevent framing of administrative interfaces, browser security configurations that block cross-frame scripting attempts, and network-level controls that restrict access to administrative ports. The ATT&CK framework categorizes this vulnerability under T1059.001 for command and scripting interpreters and T1566 for credential harvesting through social engineering attacks, highlighting the multi-layered nature of the threat. Security teams should also consider implementing web application firewalls specifically configured to detect and block cross-frame scripting attempts, as well as conducting regular security assessments to identify similar vulnerabilities in other administrative interfaces within their enterprise infrastructure.
