CVE-2025-6876 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Best Salon Management System, specifically within the /panel/add-category.php file. The vulnerability arises from improper sanitization or validation of the 'Name' parameter, which is used in SQL queries without adequate protection. This allows an attacker to inject malicious SQL code remotely, potentially manipulating the backend database. The vulnerability does not require user interaction or authentication, making it accessible to unauthenticated remote attackers. The CVSS 4.0 score of 5.3 (medium severity) reflects that the attack vector is network-based with low attack complexity and no privileges or user interaction needed. The impact on confidentiality, integrity, and availability is limited but present at a low level, indicating that while the vulnerability could allow data manipulation or unauthorized data access, it may not lead to full system compromise or widespread disruption. No public exploits are currently known to be actively used in the wild, but the exploit details have been disclosed publicly, increasing the risk of exploitation. The lack of available patches or vendor-provided mitigations further elevates the risk for users of this system. Given the nature of the product—a salon management system—this vulnerability could expose sensitive customer data, appointment details, or business information if exploited.

For European organizations using the SourceCodester Best Salon Management System, this vulnerability could lead to unauthorized access or modification of customer and business data stored within the system. This may result in breaches of personal data protected under GDPR, leading to regulatory penalties and reputational damage. The ability to inject SQL commands remotely without authentication increases the risk of data leakage or corruption. Although the system is niche, salons and small businesses across Europe relying on this software could face operational disruptions or data integrity issues. The exposure of customer personal information, including contact details and appointment histories, could also facilitate further targeted attacks such as phishing. The medium severity rating suggests that while the threat is significant, it may not lead to full system takeover or widespread network compromise. However, the lack of patches and public exploit availability means organizations must act proactively to mitigate risk.

Organizations should immediately audit their use of the SourceCodester Best Salon Management System version 1.0 and isolate or restrict access to the /panel/add-category.php functionality if possible. Since no official patches are currently available, applying web application firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'Name' parameter is critical. Input validation and sanitization should be implemented at the application level to reject or escape malicious input. Network segmentation can limit exposure of the management system to only trusted internal users or IP addresses. Regular database backups should be maintained to enable recovery in case of data corruption. Monitoring logs for unusual database queries or failed injection attempts can provide early detection of exploitation attempts. Organizations should also consider migrating to alternative, actively maintained salon management solutions with secure coding practices. Finally, raising awareness among staff about the risks and signs of exploitation can help in early identification and response.
