CVE-2010-2600 in BlackBerry Desktop Software
Summary
by MITRE
Untrusted search path vulnerability in BlackBerry Desktop Software before 6.0.0.47 allows local users, and possibly remote attackers, to execute arbitrary code and conduct DLL hijacking attacks via a Trojan horse DLL that is located in the same folder as a file that is processed by Blackberry.

The vulnerability identified as CVE-2010-2600 represents a critical untrusted search path weakness in BlackBerry Desktop Software versions prior to 6.0.0.47. This flaw stems from the software's improper handling of dynamic link library (dll) loading mechanisms during file processing operations. The vulnerability specifically affects the desktop software's ability to securely locate and load required libraries, creating an exploitable condition where malicious actors can place specially crafted dll files in the same directory as target files being processed by the BlackBerry software. This type of vulnerability falls under the CWE-427 category of Untrusted Search Path, which is classified as a significant security weakness that can lead to privilege escalation and arbitrary code execution. The issue is particularly concerning because it can potentially be exploited by both local users with system access and remote attackers who can influence the file processing environment through various attack vectors.
The technical exploitation of this vulnerability occurs when the BlackBerry Desktop Software processes files that are located in directories containing malicious dll files. When the software attempts to load required libraries for processing these files, it follows an insecure search order that prioritizes the current working directory over system directories. This insecure practice allows an attacker to place a malicious dll file with the same name as a legitimate dll that the software expects to load, effectively hijacking the library loading process. The attacker can leverage this condition to execute arbitrary code with the privileges of the user running the BlackBerry Desktop Software. This technique aligns with the ATT&CK framework's T1059.001 and T1574.002 tactics, which cover execution through command and scripting interpreters and hijacking execution flow through dynamic link library loading respectively.
The operational impact of this vulnerability extends beyond simple code execution to encompass potential system compromise and data exfiltration capabilities. Local users with access to the system can exploit this weakness to escalate privileges and gain unauthorized access to sensitive information stored on the device. Remote attackers who can influence the file processing environment through social engineering, malicious file sharing, or web-based attacks can leverage this vulnerability to gain persistent access to target systems. The vulnerability's exploitation can lead to complete system compromise, especially when combined with other attack techniques, and represents a significant risk for organizations relying on BlackBerry Desktop Software for device management and synchronization. This weakness particularly affects enterprise environments where BlackBerry devices are commonly used for business communication and data management, making it a prime target for advanced persistent threat actors.
Mitigation strategies for CVE-2010-2600 should focus on immediate software updates and operational security measures. The most effective solution involves upgrading to BlackBerry Desktop Software version 6.0.0.47 or later, which addresses the untrusted search path vulnerability through proper dll loading mechanisms. Organizations should implement strict access controls and user permissions to limit local user privileges that could enable exploitation. Network security controls should monitor for suspicious file transfers and processing activities that might indicate exploitation attempts. System administrators should conduct regular security assessments to identify and remediate similar vulnerabilities in other software applications. The vulnerability also underscores the importance of secure coding practices and proper library loading mechanisms, which should be enforced through security development lifecycle processes. Additionally, implementing application whitelisting and mandatory access controls can provide defense-in-depth measures against similar exploitation techniques, aligning with the ATT&CK framework's defensive strategies for preventing privilege escalation and code execution attacks.
