CVE-2025-11505 is a SQL injection vulnerability identified in version 1.1 of the PHPGurukul Beauty Parlour Management System, specifically within the /admin/new-appointment.php script. The vulnerability arises from improper sanitization of the 'delid' parameter, which is used in SQL queries without adequate validation or parameterization. This flaw allows an unauthenticated remote attacker to inject malicious SQL code, potentially enabling unauthorized data access, modification, or deletion within the underlying database. The vulnerability does not require user interaction or privileges, making it easier to exploit. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, and no required privileges or user interaction, but limited impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, a public exploit is available, increasing the risk of attacks. The affected product is niche software used primarily by beauty parlour businesses to manage appointments and related operations. The vulnerability's exploitation could lead to data leakage of customer information, appointment details, or administrative data, and could disrupt business operations through data manipulation or deletion. The lack of patches or vendor advisories necessitates immediate mitigation by users. The vulnerability highlights the importance of secure coding practices, especially input validation and use of prepared statements in PHP applications.

For European organizations using the PHPGurukul Beauty Parlour Management System 1.1, this vulnerability could lead to unauthorized access to sensitive customer and business data stored in the backend database. Confidentiality breaches may expose personal customer information, potentially violating GDPR and other data protection regulations, leading to legal and financial repercussions. Integrity of data could be compromised by unauthorized modification or deletion of appointment records, affecting business operations and customer trust. Availability might be impacted if attackers manipulate or corrupt database contents, causing service disruptions. Small and medium-sized beauty parlour businesses, which are common in Europe, may lack dedicated cybersecurity resources, increasing their vulnerability. The presence of a public exploit increases the likelihood of opportunistic attacks, including automated scanning and exploitation by cybercriminals. The impact is particularly significant for businesses in countries with large beauty and wellness sectors, where customer data protection is critical. Additionally, reputational damage from a breach could have long-term effects on customer retention and regulatory compliance.

To mitigate CVE-2025-11505, organizations should immediately audit the /admin/new-appointment.php file and specifically the handling of the 'delid' parameter. Implement strict input validation and sanitization to ensure only expected numeric or alphanumeric values are accepted. Replace any dynamic SQL queries with parameterized prepared statements or use stored procedures to prevent injection. Restrict access to the admin interface by IP whitelisting, VPN, or multi-factor authentication to reduce exposure. Monitor logs for unusual database queries or repeated failed attempts that might indicate exploitation attempts. If possible, upgrade to a patched version or contact the vendor for security updates. Conduct regular security assessments and penetration tests focusing on web application vulnerabilities. Educate staff on the risks of SQL injection and enforce secure coding standards for any customizations. Finally, ensure regular backups of databases are maintained to enable recovery in case of data corruption or deletion.
