The CVE-2007-2549 vulnerability represents a critical SQL injection flaw discovered in the TurnkeyWebTools SunShop Shopping Cart version 4.0, specifically within the index.php script. This vulnerability exposes the application to remote code execution attacks through improper input validation mechanisms that fail to sanitize user-supplied data before incorporating it into database queries. The flaw manifests when attackers manipulate the c or quantity parameters to inject malicious SQL commands that can be executed against the underlying database system.
This vulnerability falls under the CWE-89 category of SQL Injection, which is classified as a fundamental weakness in software applications that allow attackers to manipulate database queries through untrusted input. The attack vector specifically targets the parameter handling mechanism in the shopping cart application, where user inputs are directly concatenated into SQL statements without proper sanitization or parameterization. The vulnerability affects both the c parameter and quantity parameter, indicating a systemic issue in how multiple input fields are processed within the application's core functionality.
The operational impact of this vulnerability is severe as it enables attackers to execute arbitrary SQL commands on the database server hosting the SunShop application. This capability allows unauthorized users to perform data manipulation, including data retrieval, modification, deletion, and potentially database schema enumeration. Attackers could extract sensitive customer information, modify product catalogs, manipulate order processing, and gain persistent access to the application's backend systems. The remote nature of the attack means that exploitation can occur from any location without requiring physical access to the server infrastructure.
From a threat modeling perspective, this vulnerability aligns with ATT&CK technique T1071.005 for Application Layer Protocol and T1190 for Exploit Public-Facing Application, representing a classic attack pattern that targets web application interfaces. The vulnerability demonstrates poor input validation practices and lack of proper database query parameterization, which are common indicators of insecure coding practices. Organizations utilizing this shopping cart solution face significant risk of data breaches and system compromise, particularly given that the vulnerability affects core commerce functionality that handles sensitive transactional data.
Mitigation strategies should focus on implementing proper input validation and parameterized queries to prevent SQL injection attacks. The most effective remediation involves replacing direct string concatenation with prepared statements or parameterized queries that separate SQL commands from data inputs. Additionally, input sanitization measures should be implemented to filter or escape special characters that could be used in injection attacks. The application should also implement proper access controls and logging mechanisms to detect and prevent unauthorized database access attempts. Regular security assessments and code reviews should be conducted to identify similar vulnerabilities in other application components and ensure that all user inputs are properly validated before processing.
