The CVE-2004-2202 vulnerability represents a critical security flaw in DUware DUclassified versions 4.0 through 4.2 that exposes the application to multiple SQL injection attack vectors. This vulnerability falls under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection weaknesses in software applications. The flaw manifests in the adDetail.asp page where the cat_id and sub_id parameters are not properly sanitized before being incorporated into database queries, creating opportunities for malicious input injection that can manipulate the underlying database operations.
The vulnerability operates by allowing remote attackers to manipulate database queries through specifically crafted input parameters that are directly concatenated into SQL statements without proper validation or escaping. When an attacker submits malicious input through the cat_id or sub_id parameters in adDetail.asp, the application fails to implement adequate input filtering mechanisms, enabling the execution of arbitrary SQL commands against the database server. Additionally, the password parameter in the login form presents another attack vector where authentication bypass attempts can be made through SQL injection techniques, potentially allowing unauthorized access to administrative functions and user accounts.
The operational impact of this vulnerability extends beyond simple data manipulation to encompass complete system compromise and unauthorized access to sensitive information. Attackers can leverage these injection points to extract confidential data including user credentials, personal information, and classified advertisements stored within the database. The authentication bypass capability particularly threatens the application's integrity by allowing unauthorized individuals to gain administrative privileges and potentially modify or delete critical system components. This vulnerability also enables command execution at the database level, which can result in complete system compromise and persistent backdoor access.
Mitigation strategies for CVE-2004-2202 should prioritize immediate implementation of proper input validation and parameterized queries to prevent SQL injection exploitation. Organizations should implement prepared statements and stored procedures throughout the application codebase to ensure that user input is properly escaped and validated before database processing occurs. The application should enforce strict input filtering mechanisms that reject or sanitize potentially malicious characters and sequences that could be used in SQL injection attacks. Additionally, implementing proper access controls and authentication mechanisms, including account lockout policies for failed login attempts, can help reduce the effectiveness of brute force and injection attacks. Regular security auditing and penetration testing of web applications should be conducted to identify and remediate similar vulnerabilities before they can be exploited by malicious actors, aligning with the ATT&CK framework's methodology for identifying and mitigating database-related attack patterns.
