The vulnerability identified as CVE-2008-3512 represents a critical SQL injection flaw within the Kleinanzeigen module of PHP-Nuke content management system. This security weakness resides in the module's handling of user input parameters, specifically the lid parameter that is processed during visit actions through the modules.php endpoint. The vulnerability stems from insufficient input validation and sanitization mechanisms that fail to properly escape or filter malicious SQL payloads submitted by remote attackers.
The technical implementation of this flaw allows malicious actors to inject arbitrary SQL commands into the database query execution flow by manipulating the lid parameter value. When the Kleinanzeigen module processes the visit action, it directly incorporates the lid parameter into SQL queries without adequate protection against injection attacks. This creates a pathway for attackers to bypass authentication mechanisms, extract sensitive data, modify database records, or even execute destructive operations on the underlying database system. The vulnerability operates at the application layer and can be exploited through HTTP requests that target the specific module endpoint.
From an operational impact perspective, this vulnerability poses significant risks to organizations using PHP-Nuke with the Kleinanzeigen module. Attackers can potentially gain unauthorized access to user accounts, personal information, and system configuration data stored within the database. The remote exploitation capability means that threat actors do not require physical access to the system or local network presence to carry out attacks. Successful exploitation could lead to complete system compromise, data exfiltration, and potential service disruption that affects the availability of the web application. The vulnerability also aligns with CWE-89 which categorizes improper neutralization of special elements used in SQL commands as a fundamental weakness in software security design.
Organizations should implement immediate mitigations including input validation and parameterized queries to address this vulnerability. The recommended approach involves sanitizing all user-supplied input parameters before incorporating them into database queries, implementing proper escape sequences for special SQL characters, and utilizing prepared statements or parameterized queries to prevent malicious SQL injection attempts. Additionally, access controls should be strengthened around the affected module, and input length restrictions should be enforced. Security monitoring should be enhanced to detect unusual patterns in database access and query execution that may indicate exploitation attempts. The remediation efforts should align with ATT&CK technique T1071.004 which covers application layer protocol manipulation and T1190 which addresses exploitation of remote services through injection vulnerabilities. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other application components and ensure comprehensive protection against SQL injection threats across the entire system architecture.
