CVE-2025-15409 identifies a SQL injection vulnerability in the Online Guitar Store 1.0 application developed by code-projects. The flaw exists in the /admin/Delete_product.php script, where the del_pro parameter is improperly sanitized, allowing attackers to inject malicious SQL code. This vulnerability can be exploited remotely without authentication or user interaction, enabling attackers to manipulate backend SQL queries. Potential consequences include unauthorized data disclosure, modification, or deletion, impacting the confidentiality, integrity, and availability of the database. The CVSS 4.0 score is 6.9 (medium severity), reflecting the lack of required privileges or user interaction but limited scope of impact (partial confidentiality, integrity, and availability). Although no known exploits are currently active in the wild, the public disclosure increases the risk of exploitation. The vulnerability primarily affects organizations running this specific version of the Online Guitar Store software, particularly those exposing the admin interface to the internet. The absence of patches or official fixes necessitates immediate mitigation through secure coding practices and access controls.

For European organizations using the affected Online Guitar Store 1.0 software, this vulnerability poses a significant risk of unauthorized access to sensitive product and possibly customer data. Attackers could alter or delete product records, disrupt e-commerce operations, or extract confidential information from the database. This could lead to financial losses, reputational damage, and regulatory non-compliance, especially under GDPR requirements for data protection. The remote, unauthenticated nature of the exploit increases the attack surface, particularly for organizations with publicly accessible admin panels. While the impact is medium severity, targeted attacks could escalate consequences if combined with other vulnerabilities or insider threats. The disruption of availability or integrity of product data could impair business continuity and customer trust in affected European markets.

1. Immediately restrict access to the /admin/Delete_product.php endpoint using network-level controls such as IP whitelisting or VPN-only access to limit exposure. 2. Implement strict input validation and sanitization on the del_pro parameter to prevent injection of malicious SQL code. 3. Refactor the code to use parameterized queries or prepared statements instead of dynamic SQL concatenation. 4. Conduct a thorough security review of all admin-facing scripts to identify and remediate similar injection flaws. 5. Monitor logs for suspicious activities targeting the del_pro parameter or admin endpoints. 6. If possible, upgrade to a patched or newer version of the software once available. 7. Employ web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this vulnerability. 8. Train development teams on secure coding practices to prevent recurrence of injection vulnerabilities.
