CVE-2025-11513 identifies a SQL injection vulnerability in the code-projects E-Commerce Website version 1.0, specifically within the /pages/supplier_update.php file. The vulnerability arises from improper sanitization of the supp_id parameter, which is directly incorporated into SQL queries without adequate validation or parameterization. This flaw allows remote attackers to inject malicious SQL code, potentially enabling unauthorized access to or manipulation of the underlying database. The vulnerability is exploitable without authentication or user interaction, making it particularly dangerous. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the ease of exploitation (network accessible, no privileges required) and the potential impact on confidentiality, integrity, and availability, though the impact is rated low in each category individually. No patches have been officially released yet, and no known exploits are reported in the wild, but public disclosure increases the likelihood of future exploitation. The vulnerability affects only version 1.0 of the product, which may limit exposure depending on the deployment footprint. The attack vector is network-based, allowing attackers to remotely execute arbitrary SQL commands, potentially leading to data leakage, unauthorized data modification, or denial of service through database corruption or crashes.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of sensitive business and customer data managed through the affected e-commerce platform. Exploitation could lead to unauthorized disclosure of supplier or transactional information, manipulation of supplier records, or disruption of e-commerce operations, impacting revenue and customer trust. Given the remote and unauthenticated nature of the attack, threat actors can exploit this vulnerability at scale if the platform is internet-facing. The impact is particularly critical for organizations handling large volumes of supplier or financial data, or those subject to stringent data protection regulations such as GDPR. Additionally, compromised e-commerce platforms can serve as a foothold for further network intrusion or lateral movement within an organization’s IT environment. The lack of a patch and public disclosure increases urgency for mitigation. The medium severity rating suggests that while the vulnerability is serious, it may not lead to full system compromise without additional factors, but the risk remains substantial.

European organizations should immediately implement the following specific mitigations: 1) Apply input validation and sanitization on the supp_id parameter to reject or properly encode malicious input. 2) Refactor the affected code to use parameterized queries or prepared statements to prevent SQL injection. 3) If patching is not yet available, deploy Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting the supp_id parameter. 4) Conduct thorough code reviews and security testing of all input handling in the e-commerce platform. 5) Monitor database logs and web server logs for unusual query patterns or repeated failed attempts to access supplier_update.php. 6) Restrict database user privileges to the minimum necessary to limit the impact of potential exploitation. 7) Consider network segmentation to isolate the e-commerce platform from critical internal systems. 8) Educate development and operations teams about secure coding practices to prevent similar vulnerabilities. 9) Prepare incident response plans to quickly address any detected exploitation attempts. These steps go beyond generic advice by focusing on immediate code-level fixes, detection, and containment strategies tailored to this specific vulnerability.
