CVE-2025-11509 is a SQL injection vulnerability identified in the code-projects E-Commerce Website version 1.0, specifically within the /pages/product_add.php script. The vulnerability arises from improper sanitization of the prod_name parameter, which is used in SQL queries without adequate validation or parameterization. This allows an attacker to inject malicious SQL code remotely, without requiring authentication or user interaction, to manipulate the backend database. Potential exploitation can lead to unauthorized data disclosure, data modification, or even complete compromise of the database server. The CVSS 4.0 score of 5.3 reflects a medium severity, considering the attack vector is network-based with low complexity and no privileges required, but with limited impact on confidentiality, integrity, and availability. Although no active exploits have been reported, the public availability of exploit code increases the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. The lack of secure coding practices in handling SQL queries is the root cause, emphasizing the need for secure development lifecycle adherence.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of customer and transactional data managed by the affected e-commerce platform. Exploitation could lead to unauthorized access to sensitive information such as customer details, payment data, and order histories, potentially resulting in financial loss, reputational damage, and regulatory penalties under GDPR. Additionally, attackers could alter or delete product information or orders, disrupting business operations and availability of services. Given the e-commerce sector's critical role in many European economies, successful exploitation could have cascading effects on supply chains and consumer trust. Organizations relying on this platform without mitigation may face increased risk of targeted attacks, especially as exploit code is publicly available. The medium severity suggests that while the impact is serious, it may be contained if proper network segmentation and monitoring are in place.

European organizations using code-projects E-Commerce Website version 1.0 should immediately implement the following mitigations: 1) Apply any available patches or updates from the vendor as soon as they are released. 2) If patches are unavailable, implement input validation and sanitization on the prod_name parameter to reject or neutralize malicious SQL input. 3) Refactor the code to use prepared statements or parameterized queries to prevent SQL injection. 4) Employ Web Application Firewalls (WAFs) with rules targeting SQL injection patterns to block exploit attempts. 5) Monitor database logs and application logs for unusual queries or errors indicative of injection attempts. 6) Restrict database user privileges to the minimum necessary to limit the impact of a successful injection. 7) Conduct security code reviews and penetration testing focused on injection vulnerabilities. 8) Educate development teams on secure coding practices to prevent similar issues in future releases.
