CVE-2025-11509 is a SQL injection vulnerability identified in version 1.0 of the code-projects E-Commerce Website, specifically within the /pages/product_add.php script. The vulnerability arises from improper sanitization of the prod_name parameter, which allows an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This flaw enables attackers to manipulate backend database queries, potentially leading to unauthorized data retrieval, data modification, or even complete database compromise depending on the database privileges. The vulnerability has been assigned a CVSS 4.0 score of 5.3, indicating a medium severity level. The attack vector is network-based with low attack complexity, no privileges required, and no user interaction needed. The impact on confidentiality, integrity, and availability is low to limited but still significant for sensitive e-commerce data. Although no known exploits have been observed in the wild, the public availability of exploit code increases the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. The lack of input validation and use of unsafe SQL query construction methods are the root causes. This vulnerability highlights the importance of secure coding practices such as parameterized queries and rigorous input validation in web applications handling sensitive data.

For European organizations operating or relying on the affected e-commerce platform, this vulnerability poses a risk of unauthorized access to customer data, including personal and payment information, which could lead to data breaches and regulatory non-compliance under GDPR. The integrity of product data and transactional records could also be compromised, potentially disrupting business operations and damaging reputation. Although the vulnerability does not require authentication, the scope is limited to installations of version 1.0 of the code-projects E-Commerce Website, which may reduce the overall exposure. However, given the critical nature of e-commerce platforms in Europe’s digital economy, even limited exploitation could have significant financial and operational consequences. The public availability of exploit code increases the urgency for mitigation. Additionally, attackers could leverage this vulnerability as a foothold for further network intrusion or lateral movement within affected organizations. The medium severity rating reflects a balance between ease of exploitation and limited but meaningful impact on confidentiality, integrity, and availability.

European organizations should immediately audit their use of the code-projects E-Commerce Website to identify any instances of version 1.0. Since no official patches are currently available, organizations should implement the following mitigations: 1) Apply strict input validation and sanitization on the prod_name parameter, ensuring only expected characters and formats are accepted. 2) Refactor the vulnerable code to use parameterized SQL queries or prepared statements to eliminate direct concatenation of user input into SQL commands. 3) Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the prod_name parameter. 4) Monitor database logs and web server logs for unusual query patterns or error messages indicative of SQL injection attempts. 5) Restrict database user privileges to the minimum necessary to limit the impact of a successful injection. 6) Conduct regular security assessments and code reviews to identify similar vulnerabilities. 7) Plan for an upgrade or patch deployment as soon as the vendor releases a fix. These steps will help reduce the risk of exploitation and protect sensitive data.
