CVE-2025-15409 is a SQL injection vulnerability identified in the code-projects Online Guitar Store version 1.0, affecting the /admin/Delete_product.php endpoint. The vulnerability arises from improper sanitization or validation of the del_pro parameter, which is used to specify a product to delete. An attacker can remotely send crafted input to this parameter, injecting malicious SQL code that alters the intended database query. This can lead to unauthorized data access, modification, or deletion within the backend database. The vulnerability does not require authentication or user interaction, making it remotely exploitable by any attacker with network access to the application. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no known exploits are currently observed in the wild, the public disclosure increases the risk of exploitation. The lack of available patches or vendor advisories necessitates immediate mitigation efforts by users of this software. The vulnerability is typical of SQL injection flaws where input parameters are directly concatenated into SQL statements without proper escaping or use of parameterized queries.

For European organizations using code-projects Online Guitar Store 1.0, this vulnerability poses a significant risk of unauthorized database access and manipulation. Attackers could extract sensitive customer data, including personal and payment information, leading to privacy violations and regulatory non-compliance under GDPR. Integrity of product and order data could be compromised, causing business disruption and loss of customer trust. Availability impacts could arise if attackers delete or corrupt critical database records, potentially causing downtime or degraded service. Small and medium enterprises using this niche e-commerce platform may lack robust security monitoring, increasing their exposure. The medium severity rating reflects the balance between ease of exploitation and partial impact scope, but the lack of authentication requirement elevates the urgency for remediation. Additionally, public disclosure without patches increases the risk of opportunistic attacks targeting vulnerable European online retailers.

Organizations should immediately audit their use of code-projects Online Guitar Store version 1.0 and identify any instances of the vulnerable /admin/Delete_product.php endpoint. Since no official patches are currently available, developers must implement secure coding practices by refactoring the del_pro parameter handling to use parameterized SQL queries or prepared statements, eliminating direct concatenation of user input. Input validation and sanitization should be enforced to reject malicious payloads. Access to the /admin/ directory should be restricted via network controls or authentication mechanisms to reduce exposure. Web application firewalls (WAFs) can be deployed with rules to detect and block SQL injection attempts targeting this parameter. Regular security testing, including automated scanning and manual code reviews, should be conducted to detect similar vulnerabilities. Organizations should monitor threat intelligence feeds for any emerging exploits and apply vendor patches promptly once available. Backup and recovery procedures must be verified to mitigate potential data loss from exploitation.
