CVE-2016-1914 in Enterprise Service
Summary
by MITRE
Multiple SQL injection vulnerabilities in the com.rim.mdm.ui.server.ImageServlet servlet in BlackBerry Enterprise Server 12 (BES12) Self-Service before 12.4 allow remote attackers to execute arbitrary SQL commands via the imageName parameter to (1) mydevice/client/image, (2) admin/client/image, (3) myapps/client/image, (4) ssam/client/image, or (5) all/client/image.

The vulnerability identified as CVE-2016-1914 represents a critical SQL injection flaw within the BlackBerry Enterprise Server 12 (BES12) Self-Service component that affects versions prior to 12.4. This vulnerability resides in the com.rim.mdm.ui.server.ImageServlet servlet, which processes image-related requests across multiple endpoints including mydevice/client/image, admin/client/image, myapps/client/image, ssam/client/image, and all/client/image. The flaw allows remote attackers to execute arbitrary SQL commands by manipulating the imageName parameter, creating a severe security risk that could compromise the entire mobile device management infrastructure.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization within the ImageServlet component. When the imageName parameter is processed through any of the specified endpoints, the application fails to properly escape or filter user-supplied input before incorporating it into SQL queries. This lack of proper parameter sanitization creates an exploitable condition where malicious actors can inject crafted SQL payloads that bypass authentication mechanisms and directly manipulate the underlying database. The vulnerability aligns with CWE-89, which specifically addresses SQL injection flaws, and demonstrates poor input validation practices that violate secure coding principles. The attack surface is particularly concerning given that the affected endpoints are accessible to remote users without requiring authentication, making the exploit trivial to execute from external networks.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to perform complete database manipulation including data retrieval, modification, deletion, and potentially privilege escalation. Attackers could leverage this vulnerability to access sensitive corporate data stored within the BES12 environment, including device information, user credentials, and enterprise communication records. The implications are particularly severe for organizations relying on BlackBerry Enterprise Server for mobile device management, as successful exploitation could lead to complete compromise of the mobile device management infrastructure. This vulnerability also aligns with ATT&CK technique T1071.004, which covers application layer protocol manipulation, and T1046, covering network service scanning, as attackers would likely first identify the vulnerable endpoints before executing their payloads.
Organizations should immediately implement mitigations including upgrading to BlackBerry Enterprise Server 12.4 or later versions that contain the necessary security patches. Additionally, network segmentation and firewall rules should be configured to restrict access to the vulnerable endpoints, particularly those exposed to external networks. Input validation should be strengthened at all application layers, with proper parameterized queries and stored procedures implemented to prevent SQL injection attacks. Security monitoring should be enhanced to detect anomalous database access patterns that might indicate exploitation attempts. The vulnerability also highlights the importance of regular security assessments and vulnerability management programs, as this flaw persisted across multiple versions of the BES12 platform and affected critical administrative functions. Organizations should also consider implementing web application firewalls and database activity monitoring solutions to provide additional layers of defense against similar injection attacks.
