The CVE-2007-4604 vulnerability represents a critical sql injection flaw in DL PayCart version 1.01 that exposes the application to remote code execution through improper input validation. This vulnerability specifically targets the viewitem.php script which processes user-supplied ItemID parameters without adequate sanitization or parameterization. The flaw enables malicious actors to inject arbitrary sql commands directly into the database query execution flow, potentially allowing full database access and manipulation. The vulnerability stems from the application's failure to properly escape or validate user input before incorporating it into sql statements, creating an attack surface where malicious input can alter the intended query behavior.
The technical implementation of this vulnerability follows standard sql injection patterns where the ItemID parameter is directly concatenated into sql queries without proper input filtering or prepared statement usage. When an attacker submits a malicious ItemID value containing sql payload characters such as single quotes, semicolons, or sql keywords, the application processes these inputs directly within the sql execution context. This design flaw allows attackers to manipulate the sql query structure and potentially execute commands that could retrieve sensitive data, modify database records, or even escalate privileges within the database environment. The vulnerability operates at the application layer and requires no special privileges to exploit, making it particularly dangerous for web applications handling sensitive transactional data.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise and business disruption. Attackers can leverage this vulnerability to extract customer information, payment details, and other confidential data stored within the DL PayCart database. The exposure of payment transaction data could lead to significant financial losses, regulatory penalties under payment card industry standards, and reputational damage. Additionally, the ability to modify database content could result in transaction manipulation, inventory falsification, or service disruption that directly impacts business operations. Organizations using this vulnerable software face potential compliance violations with data protection regulations such as pci dss and gdpr due to inadequate input validation practices.
Mitigation strategies for CVE-2007-4604 should focus on implementing proper input validation and parameterized queries to prevent sql injection attacks. Organizations must immediately patch or upgrade to DL PayCart versions that address this vulnerability through proper input sanitization and prepared statement usage. The implementation of web application firewalls and input validation rules can provide additional protective layers against such attacks. Security best practices recommend using parameterized queries or stored procedures instead of dynamic sql construction, along with input validation that filters out potentially malicious characters. This vulnerability aligns with CWE-89 which categorizes sql injection as a fundamental weakness in software design, and maps to ATT&CK technique T1190 for exploitation of vulnerabilities in web applications. Regular security assessments and code reviews should be conducted to identify similar input validation flaws in other application components, ensuring comprehensive protection against sql injection threats across the entire software ecosystem.
