The CVE-2015-2102 vulnerability represents a critical sql injection flaw in ClipBucket version 2.7 RC3, specifically within the view_item.php script that processes user input through the item parameter. This vulnerability falls under the common weakness enumeration CWE-89 which categorizes sql injection as a serious security weakness that allows attackers to manipulate database queries by injecting malicious sql code. The flaw exists due to insufficient input validation and sanitization mechanisms that fail to properly escape or filter user-supplied data before incorporating it into database queries.
The technical exploitation of this vulnerability occurs when remote attackers submit malicious input through the item parameter in view_item.php, which then gets directly embedded into sql queries without proper sanitization. This allows threat actors to execute arbitrary sql commands on the underlying database system, potentially leading to unauthorized data access, data modification, or complete database compromise. The vulnerability is particularly dangerous because it enables attackers to bypass authentication mechanisms and gain elevated privileges within the application's database layer.
The operational impact of CVE-2015-2102 extends beyond simple data theft, as successful exploitation can result in complete system compromise and unauthorized access to sensitive user information. Attackers can leverage this vulnerability to extract user credentials, personal data, and other confidential information stored within the ClipBucket database. The vulnerability also enables attackers to modify or delete database records, potentially causing data integrity issues and service disruption. Given that ClipBucket is a media sharing platform, the compromised data could include user profiles, uploaded content metadata, and system configuration details that could be used for further attacks.
Security professionals should implement multiple layers of mitigation strategies to address this vulnerability. The primary remediation involves input validation and parameterized queries to ensure that user input cannot be interpreted as sql commands. This aligns with the ATT&CK framework's mitigation techniques for preventing command injection attacks. Additionally, implementing proper output encoding, using stored procedures, and applying the principle of least privilege for database accounts can significantly reduce the attack surface. Regular security patching and vulnerability assessments should be conducted to prevent similar issues in future versions of the application. Organizations using ClipBucket should also consider implementing web application firewalls and monitoring systems to detect and block suspicious sql injection attempts. The vulnerability demonstrates the importance of proper input sanitization and highlights the need for comprehensive security testing throughout the software development lifecycle to prevent such critical flaws from reaching production environments.
