CVE-2025-6668 is a critical SQL Injection vulnerability identified in version 1.0 of the code-projects Inventory Management System. The flaw exists in the /php_action/fetchSelectedBrand.php file, specifically through the manipulation of the 'brandId' parameter. This parameter is not properly sanitized or validated, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. Exploiting this vulnerability could enable an attacker to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data disclosure, data modification, or even complete compromise of the database server. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no active exploits have been reported in the wild yet. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low attack complexity, and no privileges or user interaction required. The impact on confidentiality, integrity, and availability is rated as low individually but collectively significant due to the potential for data leakage and manipulation. The vulnerability affects only version 1.0 of the Inventory Management System, which is typically deployed in small to medium-sized enterprises for managing inventory data, including product brands and related information. Given the nature of SQL injection, attackers could leverage this flaw to extract sensitive business data or corrupt inventory records, disrupting business operations and causing financial and reputational damage.

For European organizations using the code-projects Inventory Management System 1.0, this vulnerability poses a tangible risk to the confidentiality and integrity of their inventory data. Successful exploitation could lead to unauthorized access to sensitive business information such as supplier details, pricing, and stock levels, which could be leveraged for industrial espionage or competitive disadvantage. Data integrity could be compromised by unauthorized modification or deletion of inventory records, potentially disrupting supply chain operations and causing financial losses. Although no known exploits are currently active, the public disclosure increases the likelihood of opportunistic attacks. Organizations in sectors with high reliance on inventory accuracy, such as manufacturing, retail, and logistics, could face operational disruptions. Additionally, regulatory compliance risks arise if personal or sensitive data is stored within the system and exposed, potentially violating GDPR requirements. The remote and unauthenticated nature of the vulnerability means attackers can exploit it without insider access, increasing the threat surface.

1. Immediate application of patches or updates from the vendor once available is critical. Since no patch links are currently provided, organizations should monitor vendor communications closely. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'brandId' parameter or the /php_action/fetchSelectedBrand.php endpoint. 3. Conduct thorough input validation and sanitization on all user-supplied parameters, especially 'brandId', employing parameterized queries or prepared statements to prevent SQL injection. 4. Restrict database user privileges associated with the Inventory Management System to the minimum necessary, avoiding use of highly privileged accounts to limit potential damage. 5. Perform regular security audits and code reviews focusing on input handling and database interactions within the Inventory Management System. 6. Monitor logs for unusual database queries or error messages indicative of injection attempts. 7. If feasible, isolate the Inventory Management System behind network segmentation to reduce exposure. 8. Educate IT and security teams about this specific vulnerability to enhance detection and response capabilities.
