CVE-2025-11614 is a SQL injection vulnerability identified in SourceCodester Best Salon Management System version 1.0. The flaw resides in the /panel/edit-appointment.php script, where the 'editid' parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This vulnerability can be exploited remotely without requiring authentication or user interaction, making it highly accessible to attackers. Successful exploitation could enable attackers to read, modify, or delete sensitive data stored in the backend database, potentially compromising appointment records, customer information, and other critical business data. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level, with low impact on confidentiality, integrity, and availability individually but combined leading to a moderate overall risk. No official patches have been released yet, but public exploit code is available, increasing the likelihood of exploitation. The vulnerability affects only version 1.0 of the product, which is typically used by small to medium-sized salon businesses for appointment and client management. The lack of authentication or user interaction requirements significantly lowers the barrier for exploitation, making it a notable risk for organizations relying on this software.

For European organizations, the exploitation of this SQL injection vulnerability could lead to unauthorized access to sensitive customer and business data, including appointment details and personal information. This could result in data breaches violating GDPR regulations, leading to legal penalties and reputational damage. Additionally, attackers might alter or delete appointment data, disrupting business operations and causing financial losses. Small and medium enterprises in the personal care sector, which commonly use such management systems, could be disproportionately affected. The availability of a public exploit increases the risk of opportunistic attacks, especially from cybercriminals targeting less-secured small business environments. The impact on confidentiality and integrity is moderate, while availability impact is limited but still possible if attackers manipulate or corrupt database contents.

Organizations should immediately implement input validation and sanitize all user-supplied data, especially the 'editid' parameter in the /panel/edit-appointment.php script. Employing parameterized queries or prepared statements is critical to prevent SQL injection. Until an official patch is released by SourceCodester, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this parameter. Conduct thorough code reviews and security testing on the affected application components. Restrict database user permissions to the minimum necessary to limit the impact of potential exploitation. Regularly monitor logs for suspicious activities related to appointment editing functions. If feasible, isolate the application in a segmented network zone to reduce exposure. Finally, maintain backups of the database to enable recovery in case of data tampering or loss.
