The vulnerability identified as CVE-2005-2415 represents a critical SQL injection flaw affecting the Contrexx content management system prior to version 1.0.5. This vulnerability exposes the system to remote code execution through specifically crafted SQL commands that can be injected via two distinct parameter vectors within different modules of the application. The flaw resides in the insufficient input validation mechanisms that fail to properly sanitize user-supplied data before incorporating it into database queries. The poll module's value parameter and the gallery module's pId parameter serve as entry points for attackers to manipulate the underlying database operations through maliciously crafted input sequences.
From a technical perspective, this vulnerability demonstrates a classic SQL injection attack vector where user-controllable input directly influences the structure of SQL queries executed by the application's backend database. The flaw operates under CWE-89 which categorizes improper neutralization of special elements used in SQL commands, and aligns with ATT&CK technique T1190 which describes exploiting vulnerabilities in applications to execute arbitrary code. The vulnerability's exploitation allows attackers to bypass authentication mechanisms, extract sensitive data, modify database content, or even escalate privileges within the system's database layer. The specific parameters mentioned indicate that the application fails to implement proper parameterized queries or input sanitization for these particular data entry points.
The operational impact of this vulnerability extends beyond simple data compromise, as successful exploitation can lead to complete system compromise and unauthorized access to sensitive information. Attackers can leverage the SQL injection to perform unauthorized database operations including data retrieval, modification, or deletion of critical system information. The vulnerability affects the core functionality of the Contrexx platform, potentially compromising all data managed through the poll and gallery modules. Organizations using affected versions face significant risk of data breaches, system integrity violations, and potential service disruption. The remote nature of the attack means that exploitation can occur without physical access to the system, making it particularly dangerous for web-facing applications.
Mitigation strategies for this vulnerability require immediate implementation of proper input validation and sanitization measures across all user-controllable parameters. The recommended approach involves transitioning to parameterized queries or prepared statements that separate SQL command structure from data values, thereby preventing malicious input from altering the intended query execution. Organizations should also implement proper access controls and database permissions to limit the impact of potential exploitation. Additionally, regular security updates and patches should be applied immediately upon availability, as this vulnerability was addressed in Contrexx version 1.0.5. Network segmentation and intrusion detection systems can provide additional layers of protection by monitoring for suspicious SQL query patterns. The vulnerability serves as a prime example of why input validation and secure coding practices must be integral components of application development lifecycle processes, particularly in enterprise content management systems where data integrity and security are paramount considerations.
