The vulnerability identified as CVE-2006-4497 represents a critical SQL injection flaw within the IwebNegar content management system version 1.1. This security weakness resides in the comments.php script which processes user comments and handles input validation improperly. The vulnerability specifically affects the id parameter that is used to retrieve and display comments, creating an exploitable entry point for malicious actors to manipulate database queries. The flaw stems from insufficient input sanitization and improper parameter handling, allowing attackers to inject malicious SQL code directly through the web interface.
This vulnerability operates at the application layer and falls under the Common Weakness Enumeration category CWE-89, which specifically addresses SQL injection weaknesses. The attack vector requires remote access to the target system and can be executed without authentication, making it particularly dangerous for web applications. The id parameter serves as the primary attack surface where user-supplied input is directly concatenated into SQL queries without proper escaping or parameterization. This allows threat actors to manipulate the intended database operations and potentially gain unauthorized access to sensitive information or execute destructive commands on the underlying database system.
The operational impact of this vulnerability extends beyond simple data theft, as it can enable complete database compromise and potentially full system control. Attackers can leverage the SQL injection to extract confidential user data, modify existing records, create new user accounts with administrative privileges, or even delete critical database tables. The vulnerability affects the integrity and confidentiality of the entire IwebNegar application, potentially exposing all user comments, personal information, and system metadata. Organizations running this vulnerable version face significant risk of data breaches, regulatory compliance violations, and potential legal consequences due to inadequate security controls.
Mitigation strategies for CVE-2006-4497 should focus on immediate patching of the IwebNegar application to the latest secure version that addresses this vulnerability. System administrators must implement proper input validation and parameterized queries to prevent SQL injection attacks, ensuring that all user-supplied data is properly escaped before being incorporated into database queries. The implementation of web application firewalls and intrusion detection systems can provide additional layers of protection, while regular security audits and code reviews should be conducted to identify similar vulnerabilities. Organizations should also consider implementing the principle of least privilege for database access, ensuring that web applications only have the minimum necessary permissions to function properly. According to the MITRE ATT&CK framework, this vulnerability maps to techniques involving command and control through database manipulation, emphasizing the importance of network segmentation and monitoring for suspicious database activity. The vulnerability highlights the critical need for secure coding practices and regular security updates to prevent exploitation of known weaknesses in web applications.
