CVE-2025-6605 is a SQL Injection vulnerability identified in SourceCodester Best Salon Management System version 1.0, specifically within the /panel/edit-staff.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is directly used in SQL queries. An attacker can remotely manipulate this parameter to inject malicious SQL code, potentially allowing unauthorized access to or modification of the backend database. The vulnerability does not require user interaction and can be exploited over the network without authentication, increasing its risk profile. However, the CVSS 4.0 vector indicates a requirement for low privileges (PR:L), suggesting that some level of access to the system is necessary to exploit the flaw. The CVSS score of 5.3 (medium severity) reflects limited impact on confidentiality, integrity, and availability, with partial impact on these security properties. No known exploits are currently observed in the wild, and no official patches or mitigations have been published by the vendor. Given the nature of SQL injection, successful exploitation could lead to unauthorized data disclosure, data manipulation, or in some cases, full system compromise depending on the database privileges and application architecture. The vulnerability is publicly disclosed, which increases the risk of exploitation by attackers scanning for vulnerable instances of this salon management software.

For European organizations using SourceCodester Best Salon Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive customer and employee data managed within the salon management platform. This could lead to breaches of personal data protected under GDPR, resulting in legal and financial penalties. Additionally, attackers could alter staff records or business-critical data, disrupting operations and damaging business reputation. Although the software targets small to medium-sized businesses in the salon and beauty industry, the impact could extend to larger chains or franchises operating across Europe. The medium severity rating suggests that while the vulnerability is exploitable, the requirement for low privileges limits the scope to insiders or users with some system access. However, if exploited, the integrity and confidentiality of the database could be compromised, potentially leading to data leakage or manipulation. The lack of patches increases exposure time, and the public disclosure may prompt opportunistic attacks. European organizations with limited cybersecurity resources may be particularly vulnerable to exploitation and subsequent operational disruption or data breaches.

1. Immediate mitigation should include restricting access to the /panel/edit-staff.php endpoint to trusted users and networks, employing network-level controls such as VPNs or IP whitelisting. 2. Implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the 'editid' parameter. 3. Conduct a thorough code review and apply input validation and parameterized queries or prepared statements to eliminate SQL injection vectors in the affected code. 4. If possible, isolate the salon management system from critical internal networks to limit lateral movement in case of compromise. 5. Monitor application logs for unusual query patterns or repeated access attempts to the vulnerable endpoint. 6. Engage with the vendor or community to obtain or develop patches and apply them promptly once available. 7. Educate staff on the risks of privilege misuse and enforce the principle of least privilege to reduce the likelihood of exploitation. 8. Regularly back up the database and verify backup integrity to enable recovery in case of data tampering.
