CVE-2007-6466 in FreeWebshop
Summary
by MITRE
Multiple SQL injection vulnerabilities in index.php in FreeWebshop 2.2.1 allow remote attackers to execute arbitrary SQL commands via (1) the prod parameter in a details action, (2) the cat parameter in a browse list action, or (3) the group parameter in a categories action. NOTE: it was later reported that MOG - Web Shop (MOG-WebShop), a product based on the same code, is also affected.

The vulnerability identified as CVE-2007-6466 represents a critical SQL injection flaw within the FreeWebshop 2.2.1 e-commerce platform that enables remote attackers to execute arbitrary SQL commands through three distinct input parameters. This vulnerability resides in the index.php file and affects multiple operational actions within the web application, specifically targeting the details, browse list, and categories functionalities. The flaw demonstrates the classic pattern of insufficient input validation where user-supplied data is directly incorporated into SQL query construction without proper sanitization or parameterization, creating an exploitable pathway for malicious actors to manipulate the underlying database operations.
The technical implementation of this vulnerability stems from the application's failure to properly escape or validate user input before incorporating it into database queries. When attackers manipulate the prod parameter during a details action, or the cat parameter during a browse list action, or the group parameter during a categories action, they can inject malicious SQL code that gets executed by the database server. This vulnerability directly maps to CWE-89 which categorizes SQL injection as a weakness where untrusted data is used in the construction of SQL queries without proper validation or escaping. The attack vector is particularly dangerous because it allows for complete database compromise, enabling attackers to extract sensitive information, modify database contents, or even escalate privileges within the database system.
The operational impact of this vulnerability extends far beyond simple data theft, as it provides attackers with comprehensive access to the web shop's backend database infrastructure. Successful exploitation could result in unauthorized access to customer information, financial data, product catalogs, and administrative credentials stored within the database. The vulnerability affects not only FreeWebshop 2.2.1 but also MOG-WebShop, a derivative product that shares the same vulnerable codebase, indicating a widespread exposure across multiple implementations of the same software architecture. This cross-product vulnerability demonstrates how code reuse in web applications can propagate security flaws across different deployments, creating a larger attack surface than initially apparent. The impact is particularly severe in e-commerce environments where database integrity and customer data protection are paramount for business operations and regulatory compliance.
Mitigation strategies for this vulnerability require immediate implementation of input validation and parameterized query construction throughout the application codebase. Organizations should implement proper input sanitization techniques including the use of prepared statements and parameterized queries to prevent user input from being interpreted as SQL code. The application should employ strict type checking and length validation for all parameters before processing, while also implementing proper error handling that does not reveal database structure information to attackers. Additionally, access controls should be strengthened through the implementation of the principle of least privilege, ensuring that database accounts used by the web application have minimal required permissions. Network-level protections such as web application firewalls and intrusion detection systems can provide additional layers of defense, while regular security audits and code reviews should be conducted to identify similar vulnerabilities in other parts of the application. The remediation process should also include updating to patched versions of FreeWebshop and MOG-WebShop where available, as well as implementing comprehensive monitoring to detect potential exploitation attempts. This vulnerability serves as a critical reminder of the importance of secure coding practices and the necessity of validating all user inputs as fundamental security controls in web application development.
