The vulnerability identified as CVE-2009-1766 represents a critical sql injection flaw within the LightOpenCMS 0.1 content management system. This weakness exists in the index.php script where user input is not properly sanitized before being incorporated into sql query constructs. The vulnerability specifically targets the id parameter which serves as an entry point for malicious sql command execution. The flaw stems from inadequate input validation and improper query construction practices that allow attackers to manipulate the sql query structure through crafted input values.
The technical implementation of this vulnerability falls under the common weakness enumeration CWE-89 which defines sql injection as the improper handling of sql queries where user-supplied data is directly concatenated into sql statements without proper sanitization or parameterization. Attackers can exploit this weakness by submitting malicious input through the id parameter that alters the intended sql query behavior. When the application processes this input, the sql injection occurs because the system fails to distinguish between legitimate sql commands and attacker-controlled sql code, potentially allowing full database access and manipulation.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise and unauthorized access to sensitive information. Remote attackers can leverage this vulnerability to execute arbitrary sql commands on the database server, potentially gaining access to user credentials, personal information, and other confidential data stored within the cms database. The attack surface is particularly concerning as it allows for privilege escalation and persistent access to the affected system. This vulnerability also enables attackers to perform data modification, deletion, and insertion operations that can severely compromise the integrity and availability of the web application.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and parameterized queries to prevent sql injection attacks. The recommended approach involves using prepared statements with parameterized queries instead of direct string concatenation, which eliminates the possibility of sql command injection through user input. Additionally, implementing proper input sanitization techniques, including whitelisting acceptable input values and employing proper escape sequences for special sql characters, can significantly reduce the risk of exploitation. Organizations should also consider implementing web application firewalls and input filtering mechanisms to detect and block malicious sql injection attempts. The vulnerability demonstrates the critical importance of following secure coding practices and adhering to established security frameworks such as those defined in the owasp top ten and mitre attack framework, which classify sql injection as one of the most prevalent and dangerous web application security flaws requiring immediate remediation.
