CVE-2025-14091 identifies a SQL injection vulnerability in the TrippWasTaken PHP-Guitar-Shop application, affecting the Product Details Page implemented in /product.php. The vulnerability is triggered by manipulation of the 'ID' parameter, which is used in SQL queries without adequate input validation or parameterization. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially enabling unauthorized data access, modification, or deletion within the underlying database. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity, with attack vector as network (remote), low attack complexity, no privileges or user interaction required, and limited impact on confidentiality, integrity, and availability. The product follows a rolling release model, complicating version tracking and patch management. The vendor has not responded to vulnerability disclosures, and no official patches or updates have been released. While no known exploits are currently active in the wild, public exploit code availability increases the risk of future attacks. This vulnerability is critical for organizations relying on PHP-Guitar-Shop for e-commerce or inventory management, as exploitation could lead to data leakage, unauthorized transactions, or service interruptions.

For European organizations, exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive customer data, including personal and payment information, potentially violating GDPR and other data protection regulations. Integrity of product and transaction data could be compromised, leading to fraudulent orders or inventory manipulation. Availability of the e-commerce platform could be disrupted by malicious queries causing database errors or crashes, impacting business continuity and customer trust. The medium severity score indicates a moderate but tangible risk, especially for small to medium enterprises using this specific software without robust compensating controls. The lack of vendor response and patches increases exposure time, making timely mitigation critical. Organizations in sectors with high reliance on online retail, such as music stores or niche e-commerce platforms, face reputational and financial risks if exploited.

European organizations should immediately audit their PHP-Guitar-Shop deployments to identify affected versions, focusing on the presence of the vulnerable commit hash or equivalent code. As no official patches exist, organizations must implement manual mitigations such as input validation and parameterized queries in the /product.php file to sanitize the 'ID' parameter. Employing Web Application Firewalls (WAFs) with SQL injection detection rules can provide an additional layer of defense against exploitation attempts. Regularly monitor logs for suspicious query patterns or anomalies related to product ID parameters. Organizations should also isolate the database with strict access controls and consider network segmentation to limit lateral movement if compromise occurs. Given the vendor's non-responsiveness, organizations should evaluate alternative e-commerce platforms with active security maintenance. Finally, ensure backups are current and tested to enable recovery in case of data integrity loss or service disruption.
