CVE-2025-15407 is a SQL injection vulnerability identified in the Online Guitar Store version 1.0 developed by code-projects. The flaw exists in the /admin/Create_category.php script, where the dre_Ctitle parameter is improperly sanitized, allowing an attacker to inject malicious SQL code remotely. This vulnerability does not require authentication or user interaction, making it accessible to any remote attacker aware of the flaw. Exploiting this vulnerability could allow attackers to manipulate backend SQL queries, potentially leading to unauthorized data disclosure, modification, or deletion within the application's database. The vulnerability impacts confidentiality, integrity, and availability to a limited extent, as indicated by the CVSS vector (VC:L, VI:L, VA:L). The vulnerability has been publicly disclosed but currently lacks known exploits in the wild, which suggests that while the risk is present, active exploitation has not yet been observed. The absence of patches or vendor advisories means organizations must implement their own mitigations. The Online Guitar Store is a niche e-commerce platform, so the affected user base is limited but still significant for those relying on this software. The vulnerability highlights the importance of secure coding practices, particularly input validation and the use of parameterized queries to prevent SQL injection attacks.

For European organizations using the affected Online Guitar Store 1.0 platform, this vulnerability poses a risk of unauthorized database access and manipulation. Attackers could extract sensitive customer data, alter product categories, or disrupt store operations, impacting business continuity and customer trust. The medium severity reflects partial impacts on confidentiality, integrity, and availability, which could lead to data breaches or service interruptions. Given the remote, unauthenticated nature of the exploit, any exposed installations are at risk without additional protective controls. The impact is more pronounced for small and medium-sized enterprises (SMEs) that may lack robust security measures. Additionally, regulatory compliance such as GDPR could be affected if personal data is compromised, leading to legal and financial consequences. The limited market penetration of this specific software reduces the overall European risk but does not eliminate it, especially in countries with active e-commerce sectors and smaller vendors who might use such niche platforms.

Organizations should immediately audit their use of the Online Guitar Store 1.0 software and restrict access to the /admin/Create_category.php endpoint, ideally limiting it to trusted internal networks or VPNs. Implement web application firewalls (WAFs) with SQL injection detection and prevention rules tailored to the dre_Ctitle parameter. Since no official patch is available, developers or administrators should review and sanitize all inputs rigorously, replacing vulnerable code with parameterized queries or prepared statements to eliminate injection vectors. Regularly monitor logs for suspicious activity targeting the admin interface. Conduct security awareness training for administrators to recognize potential exploitation attempts. If feasible, upgrade to a newer, secure version of the software or migrate to a more secure e-commerce platform. Finally, ensure backups of the database are maintained and tested to enable recovery in case of data manipulation or loss.
