CVE-2025-6880 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Best Salon Management System, specifically within the /panel/edit-tax.php file. The vulnerability arises from improper sanitization or validation of the 'editid' parameter, which is used in SQL queries without adequate protection against injection attacks. This flaw allows an unauthenticated remote attacker to manipulate the SQL query logic by injecting malicious SQL code through the 'editid' parameter. The vulnerability does not require user interaction or prior authentication, making it accessible remotely over the network. Exploiting this vulnerability could enable attackers to read, modify, or delete data within the underlying database, potentially leading to unauthorized data disclosure, data corruption, or disruption of service. Although the CVSS 4.0 base score is 5.3 (medium severity), the exploitability is relatively straightforward due to low attack complexity and no authentication requirement. The vulnerability affects only version 1.0 of the product, and no official patches or fixes have been published as of the disclosure date. No known exploits are currently reported in the wild, but public disclosure increases the risk of exploitation attempts.

For European organizations using the SourceCodester Best Salon Management System version 1.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their salon management data. Attackers exploiting this SQL Injection could gain unauthorized access to sensitive customer information, financial records, or internal business data stored in the database. This could lead to data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and financial losses. Additionally, attackers could alter or delete critical data, disrupting business operations and service delivery. Given the remote and unauthenticated nature of the attack, the threat surface is broad, especially for organizations that expose the management panel to the internet or have weak network segmentation. The medium CVSS score suggests moderate impact, but the actual damage could escalate depending on the database contents and the organization's reliance on the affected system.

1. Immediate mitigation should include restricting external access to the /panel/edit-tax.php endpoint via network controls such as firewalls or VPNs to limit exposure. 2. Implement input validation and parameterized queries (prepared statements) in the application code to sanitize the 'editid' parameter and prevent SQL injection. 3. If source code modification is not feasible immediately, deploy a Web Application Firewall (WAF) with custom rules to detect and block SQL injection patterns targeting the vulnerable parameter. 4. Conduct a thorough security audit of the entire application to identify and remediate similar injection flaws. 5. Monitor logs for suspicious activities related to SQL injection attempts and unusual database queries. 6. Plan and apply vendor patches or updates once available. 7. Educate developers and administrators on secure coding practices and the importance of input sanitization. 8. Consider migrating to a more secure or updated salon management solution if the vendor does not provide timely fixes.
