CVE-2025-7138 is a critical SQL Injection vulnerability identified in version 1.0 of the SourceCodester Best Salon Management System, specifically within the /panel/admin-profile.php file. The vulnerability arises from improper sanitization or validation of the 'adminname' parameter, which can be manipulated by an attacker to inject malicious SQL queries. This flaw allows remote attackers to execute arbitrary SQL commands on the backend database without requiring user interaction or authentication, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:L). The vulnerability impacts the confidentiality, integrity, and availability of the database, potentially enabling attackers to extract sensitive information, modify or delete data, or disrupt system operations. Although the CVSS score is rated medium (5.3), the exploitability is relatively straightforward due to low attack complexity and no need for user interaction. The vulnerability has been publicly disclosed, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The absence of patches or mitigation links suggests that organizations using this software must proactively implement protective measures. Given the nature of the application—a salon management system—compromise could expose customer data, employee information, and business operational data, which are critical for maintaining privacy and trust.

For European organizations utilizing the SourceCodester Best Salon Management System, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to personal customer data, including contact details and potentially payment information, violating GDPR requirements and resulting in legal and financial penalties. Data integrity could be compromised, affecting appointment schedules, billing records, and employee profiles, disrupting business operations and customer service. Availability impacts could arise if attackers execute destructive SQL commands, leading to system downtime and loss of revenue. The reputational damage from a data breach in the service industry could be substantial, especially in privacy-conscious European markets. Additionally, the medium CVSS score may underestimate the real-world impact, as the vulnerability allows remote exploitation without user interaction, increasing the attack surface. Organizations may also face increased scrutiny from regulators if they fail to secure client data adequately.

Given the lack of official patches, European organizations should immediately implement the following specific mitigations: 1) Apply strict input validation and sanitization on the 'adminname' parameter at the web application firewall (WAF) or reverse proxy level to block SQL injection payloads. 2) Employ parameterized queries or prepared statements within the application code if source code access and modification are possible. 3) Restrict database user privileges to the minimum necessary, preventing unauthorized data manipulation or extraction. 4) Monitor database logs and web server logs for unusual query patterns or repeated failed attempts targeting the admin-profile.php endpoint. 5) Isolate the management system network segment to limit exposure and access only to trusted administrative users. 6) Conduct regular security assessments and penetration testing focused on injection flaws. 7) Prepare incident response plans specific to data breaches involving customer information. 8) Engage with the vendor or community to obtain or develop patches and updates. These measures should be prioritized to reduce the attack surface and limit potential damage until an official patch is released.
