CVE-2025-6604 is a SQL Injection vulnerability identified in SourceCodester Best Salon Management System version 1.0, specifically within the /panel/add-staff.php file. The vulnerability arises from improper sanitization or validation of the 'Name' parameter, which is susceptible to malicious SQL code injection. An attacker can remotely exploit this flaw without requiring authentication or user interaction, by directly manipulating the input sent to the vulnerable parameter. The injection can lead to unauthorized access or modification of the backend database, potentially allowing attackers to extract sensitive data, alter records, or disrupt database integrity. Although the CVSS 4.0 score is rated at 5.3 (medium severity), the vulnerability's remote exploitability and lack of required privileges increase its risk profile. The disclosed exploit details have been made public, increasing the likelihood of exploitation attempts. The vulnerability affects only version 1.0 of the product, and no official patches or mitigations have been published by the vendor at this time. The absence of known exploits in the wild suggests limited active exploitation currently, but the public disclosure elevates the threat level for organizations using this software.

For European organizations utilizing the SourceCodester Best Salon Management System 1.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their customer and operational data. Salons and related service providers often store personal client information, appointment schedules, and payment data, which could be exposed or manipulated through SQL injection attacks. Exploitation could lead to data breaches, financial fraud, reputational damage, and operational disruptions. Given the remote and unauthenticated nature of the attack vector, threat actors could automate exploitation attempts at scale. This is particularly concerning for small and medium-sized enterprises (SMEs) in the personal care sector that may lack robust cybersecurity defenses. Additionally, compromised salon management systems could serve as pivot points for lateral movement within organizational networks, potentially exposing other sensitive systems. The medium CVSS score might underestimate the practical impact due to the ease of exploitation and the sensitive nature of the data involved.

1. Immediate mitigation should include disabling or restricting access to the vulnerable /panel/add-staff.php endpoint until a patch is available. 2. Implement Web Application Firewall (WAF) rules specifically targeting SQL injection patterns on the 'Name' parameter to block malicious payloads. 3. Conduct input validation and sanitization on all user inputs, especially those interacting with the database, employing parameterized queries or prepared statements to prevent injection. 4. Monitor database logs and application logs for unusual queries or failed injection attempts to detect exploitation attempts early. 5. If possible, isolate the salon management system network segment to limit lateral movement in case of compromise. 6. Engage with the vendor or community to obtain or develop patches or updates addressing this vulnerability. 7. Educate staff about the risks and signs of compromise related to this system. 8. Regularly back up the database and system configurations to enable recovery in case of data tampering or loss. These measures go beyond generic advice by focusing on immediate containment, detection, and long-term remediation tailored to the specific vulnerable component and its operational context.
