CVE-2025-6607 is a SQL Injection vulnerability identified in version 1.0 of the SourceCodester Best Salon Management System, specifically within an unspecified function in the /panel/stock.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which allows an attacker to inject malicious SQL queries remotely without requiring user interaction or authentication. This flaw enables an attacker to manipulate backend database queries, potentially leading to unauthorized data access, data modification, or disruption of database operations. Although the CVSS 4.0 base score is 5.3 (medium severity), the vulnerability is classified as critical in the description, indicating a significant risk if exploited. The exploit code has been publicly disclosed, increasing the likelihood of exploitation attempts. The vulnerability does not require authentication or user interaction, and the attack vector is network-based, making it accessible to remote attackers. The impact on confidentiality, integrity, and availability is limited but present, as indicated by the CVSS vector components (VC:L, VI:L, VA:L), meaning partial loss of these security properties is possible. No patches or fixes have been linked yet, and no known exploits are reported in the wild at the time of publication. The vulnerability affects only version 1.0 of the product, which is a niche management system targeted at salon businesses, typically used for inventory and stock management.

For European organizations, especially small and medium-sized enterprises (SMEs) operating in the beauty and salon industry, this vulnerability poses a tangible risk. Exploitation could lead to unauthorized access to sensitive business data such as inventory records, customer information, and transaction histories. This could result in data breaches, loss of customer trust, and potential regulatory non-compliance under GDPR if personal data is exposed. Additionally, attackers could manipulate stock data, causing operational disruptions or financial losses. While the product is niche, salons in Europe that rely on this system without timely updates or mitigations are vulnerable. The medium CVSS score suggests moderate impact, but the public availability of exploit code elevates the urgency. The vulnerability could also be leveraged as a foothold for further network intrusion if the salon management system is connected to broader corporate networks. Given the limited scope of affected versions and the product's market penetration, the overall impact on large enterprises is minimal, but SMEs and local businesses are at higher risk.

1. Immediate mitigation should include restricting external network access to the /panel/stock.php endpoint via firewall rules or web application firewalls (WAFs) to limit exposure. 2. Implement input validation and parameterized queries or prepared statements in the source code to prevent SQL injection. Since no official patch is currently available, organizations should review and sanitize all inputs related to the 'ID' parameter manually if possible. 3. Monitor web server and database logs for unusual or suspicious queries targeting the 'ID' parameter to detect exploitation attempts early. 4. Segregate the salon management system network segment from critical corporate infrastructure to minimize lateral movement in case of compromise. 5. Educate staff about the risk and ensure backups of the database are performed regularly to enable recovery from potential data tampering. 6. Engage with the vendor or community to obtain patches or updates as soon as they become available. 7. Consider deploying runtime application self-protection (RASP) tools or database activity monitoring solutions to detect and block SQL injection attempts dynamically.
