CVE-2025-7137 is a SQL Injection vulnerability identified in SourceCodester Best Salon Management System version 1.0. The vulnerability exists in the /panel/schedule-staff.php file, specifically through the manipulation of the 'staff_id' parameter. An attacker can remotely exploit this flaw without requiring authentication or user interaction. The vulnerability allows the injection of malicious SQL code, which can lead to unauthorized access to the backend database. This may result in data leakage, data modification, or even complete compromise of the database server depending on the privileges of the database user. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no authentication required (AT:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The exploit has been publicly disclosed, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The vulnerability is rated medium severity with a CVSS score of 5.3, reflecting moderate risk due to the partial impact and ease of exploitation but limited scope and privileges required.

For European organizations using the SourceCodester Best Salon Management System 1.0, this vulnerability poses a significant risk to the confidentiality and integrity of customer and staff data managed within the system. Salons and related businesses often store personal identifiable information (PII), appointment schedules, and potentially payment-related data. Exploitation could lead to data breaches, reputational damage, regulatory penalties under GDPR, and operational disruptions. Since the vulnerability allows remote exploitation without authentication, attackers could leverage this flaw to extract sensitive data or manipulate scheduling information, potentially causing business interruptions. The partial impact on availability could also affect service continuity. Given the public disclosure of the exploit, European organizations face an increased threat level, especially those with limited cybersecurity defenses or outdated software management practices.

1. Immediate upgrade or patching: Although no official patch links are provided, organizations should monitor SourceCodester for security updates or patches addressing CVE-2025-7137 and apply them promptly. 2. Input validation and parameterized queries: Developers or administrators with access to the source code should implement strict input validation and use prepared statements or parameterized queries to prevent SQL injection. 3. Web application firewall (WAF): Deploy a WAF with rules specifically designed to detect and block SQL injection attempts targeting the 'staff_id' parameter or similar inputs. 4. Network segmentation and access controls: Restrict access to the management system panel to trusted IP addresses or VPN connections to reduce exposure. 5. Monitoring and logging: Enable detailed logging of database queries and web requests to detect anomalous activities indicative of SQL injection attempts. 6. Incident response readiness: Prepare to respond to potential data breaches by having data backup, forensic capabilities, and notification procedures aligned with GDPR requirements. 7. Vendor engagement: Engage with SourceCodester to obtain official guidance and patches, and consider alternative salon management solutions if timely remediation is not available.
