CVE-2025-11503 identifies a SQL injection vulnerability in PHPGurukul Beauty Parlour Management System version 1.1. The vulnerability resides in the /admin/manage-services.php script, where the delid parameter is improperly sanitized, allowing an attacker to inject malicious SQL code. This injection flaw enables remote attackers to manipulate backend database queries without requiring authentication or user interaction. Exploiting this vulnerability could allow attackers to extract sensitive information, modify or delete database records, or disrupt service availability. The vulnerability has a CVSS 4.0 base score of 6.9, reflecting medium severity, with network attack vector, low attack complexity, and no privileges or user interaction needed. While no known exploits are currently active in the wild, the public disclosure increases the likelihood of exploitation attempts. The affected product is primarily used by small and medium businesses in the beauty and wellness sector to manage services, appointments, and client data, making the confidentiality and integrity of customer information a critical concern. The vulnerability’s exploitation could lead to data breaches, loss of customer trust, regulatory penalties under GDPR, and operational disruptions.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of customer and business data managed by the Beauty Parlour Management System. Exploitation could result in unauthorized access to personal client information, including names, contact details, and service histories, potentially violating GDPR requirements. Data manipulation or deletion could disrupt business operations, leading to financial losses and reputational damage. The ease of remote exploitation without authentication increases the threat level, especially for organizations lacking robust network segmentation or access controls. Small and medium enterprises in the beauty sector across Europe, which may have limited cybersecurity resources, are particularly vulnerable. Additionally, compromised systems could be leveraged as pivot points for broader network intrusions, amplifying the impact. Regulatory scrutiny in Europe regarding data protection further elevates the consequences of such a breach.

1. Apply vendor patches or updates as soon as they become available to address the SQL injection vulnerability directly. 2. If patches are not yet available, implement web application firewall (WAF) rules to detect and block malicious SQL injection payloads targeting the delid parameter. 3. Restrict access to the /admin/manage-services.php interface by IP whitelisting or VPN-only access to reduce exposure. 4. Conduct thorough input validation and parameterized query implementation in the application code to prevent injection attacks. 5. Regularly audit and monitor database logs and web server logs for suspicious activities related to SQL injection attempts. 6. Educate administrative users about the risks and signs of exploitation to enable early detection. 7. Implement network segmentation to isolate critical management systems from general user networks. 8. Prepare an incident response plan specific to web application attacks to ensure rapid containment and recovery.
