CVE-2025-11506 identifies a SQL injection vulnerability in PHPGurukul Beauty Parlour Management System version 1.1, specifically within the /admin/search-appointment.php script. The vulnerability arises from insufficient input validation and sanitization of the 'searchdata' parameter, which is used directly in SQL queries. This flaw allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially leading to unauthorized data disclosure, data modification, or database corruption. The vulnerability does not require any privileges or user interaction, making it highly accessible for exploitation. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, and no required authentication. The impact affects confidentiality, integrity, and availability, though with limited scope and no scope change. Although no known active exploitation in the wild has been reported, public exploit code availability increases the risk of future attacks. The lack of official patches necessitates immediate mitigation through input validation, query parameterization, or web application firewalls. This vulnerability is particularly relevant for organizations relying on this management system for appointment scheduling and customer data management, as exploitation could expose sensitive client information and disrupt business operations.

For European organizations, the impact of CVE-2025-11506 could be significant, especially for small and medium enterprises in the beauty and wellness sector that use the PHPGurukul Beauty Parlour Management System. Exploitation could lead to unauthorized access to sensitive customer data, including personal and appointment information, potentially violating GDPR and other data protection regulations. Data integrity could be compromised, resulting in altered or deleted appointment records, which may disrupt business operations and damage customer trust. Availability impacts could arise if attackers execute destructive SQL commands, causing service outages. The reputational damage and potential regulatory fines from data breaches could be substantial. Given the remote and unauthenticated nature of the exploit, attackers could easily target vulnerable systems across Europe, increasing the risk of widespread compromise. Organizations lacking robust monitoring and incident response capabilities may face prolonged exposure and damage.

Since no official patches are currently available for this vulnerability, European organizations should implement immediate compensating controls. First, apply strict input validation and sanitization on the 'searchdata' parameter to prevent malicious SQL code injection. Employ prepared statements or parameterized queries to ensure SQL commands are executed safely. Deploy Web Application Firewalls (WAFs) configured to detect and block SQL injection attempts targeting the affected endpoint. Conduct thorough code reviews and security testing of the application to identify and remediate similar vulnerabilities. Restrict access to the /admin/search-appointment.php page using network segmentation or IP whitelisting to limit exposure. Monitor logs for unusual query patterns or failed SQL commands indicative of exploitation attempts. Educate staff on the risks and signs of SQL injection attacks. Finally, plan for an upgrade or migration to a patched or more secure management system version once available.
