The CVE-2009-3042 vulnerability represents a critical SQL injection flaw discovered in the Open Computer and Software Inventory NG (OCS NG) version 1.02.1 web application. This vulnerability specifically targets the machine.php script which serves as a core component for managing and inventorying computer systems within the OCS NG framework. The flaw manifests when the application fails to properly sanitize user input passed through the systemid parameter, creating an exploitable condition that enables malicious actors to inject arbitrary SQL commands into the backend database operations. This vulnerability operates through a distinct attack vector compared to CVE-2009-3040, indicating separate code paths within the application's input handling mechanisms that both present significant security risks.
The technical implementation of this vulnerability stems from improper input validation and sanitization practices within the machine.php script. When a user submits a request containing a systemid parameter, the application directly incorporates this value into SQL query construction without adequate filtering or parameterization. This lack of input sanitization creates a direct pathway for attackers to manipulate the database query structure by injecting malicious SQL syntax. The vulnerability falls under the CWE-89 category of SQL Injection, specifically representing a classic case where user-controllable data enters the application's database layer without proper validation, allowing for unauthorized data access, modification, or deletion operations.
The operational impact of this vulnerability extends beyond simple data compromise, as it provides attackers with elevated privileges within the targeted OCS NG environment. Remote attackers can leverage this vulnerability to execute arbitrary SQL commands, potentially gaining access to sensitive inventory data, user credentials, system configurations, and other confidential information stored within the database. The implications are particularly severe given that OCS NG systems typically manage comprehensive inventory data for organizations, making the compromised environment a valuable target for attackers seeking to expand their access within enterprise networks. The vulnerability's remote exploitability means that attackers can initiate attacks from outside the network perimeter without requiring local access or authentication credentials.
Security mitigations for CVE-2009-3042 should prioritize immediate implementation of input validation and parameterized query approaches to prevent SQL injection attacks. Organizations must ensure that all user-supplied input, particularly parameters like systemid, undergo rigorous sanitization before being incorporated into database operations. The recommended approach involves implementing proper parameterized queries or prepared statements that separate SQL command structure from data values, effectively neutralizing the injection threat. Additionally, access controls should be strengthened to limit database access permissions for the application, following the principle of least privilege. Regular security audits and code reviews should be conducted to identify similar input validation vulnerabilities, while implementing web application firewalls can provide additional protection layers. This vulnerability aligns with ATT&CK technique T1190 for Exploit Public-Facing Application, emphasizing the need for comprehensive application security measures to protect against remote exploitation vectors targeting web applications.
