CVE-2025-15410 is a SQL injection vulnerability identified in the Online Guitar Store version 1.0 developed by code-projects. The vulnerability resides in the /login.php script, where the L_email parameter is improperly sanitized, allowing an attacker to inject malicious SQL code remotely without requiring authentication or user interaction. This injection can manipulate backend SQL queries, potentially exposing or altering sensitive data stored in the database. The vulnerability has a CVSS 4.0 base score of 6.9, indicating medium severity, with attack vector as network (remote), low attack complexity, no privileges or user interaction needed, and limited impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, a public exploit is available, increasing the risk of attacks. The vulnerability affects only version 1.0 of the Online Guitar Store, which is a niche e-commerce platform. No official patches or updates have been linked yet, requiring users to implement alternative mitigations. The vulnerability highlights the importance of input validation and parameterized queries in web applications to prevent SQL injection attacks.

If exploited, this SQL injection vulnerability could allow attackers to access, modify, or delete sensitive information stored in the Online Guitar Store's backend database, including user credentials, personal data, and transaction records. This compromises confidentiality and integrity, and may also disrupt service availability if database operations are manipulated maliciously. The lack of authentication and user interaction requirements makes exploitation straightforward, increasing the risk of automated or mass attacks. Organizations using this software risk data breaches, reputational damage, and potential regulatory penalties, especially if customer data is exposed. The impact is limited to systems running the vulnerable version, but the presence of a public exploit increases the likelihood of opportunistic attacks.

Since no official patches are currently available, organizations should immediately implement input validation and sanitization on the L_email parameter to prevent SQL injection. Employ parameterized queries or prepared statements in the /login.php code to ensure user inputs cannot alter SQL commands. Conduct a thorough code review of all input handling in the application to identify and remediate similar vulnerabilities. Restrict database user privileges to the minimum necessary to limit damage if exploited. Monitor web server logs for suspicious activity targeting the L_email parameter or /login.php endpoint. Consider deploying a web application firewall (WAF) with rules to detect and block SQL injection attempts. If possible, isolate the vulnerable application in a segmented network zone to reduce exposure. Plan for an update or patch from the vendor and test it promptly upon release.
