CVE-2025-11505 identifies a SQL injection vulnerability in PHPGurukul Beauty Parlour Management System version 1.1. The vulnerability exists in the /admin/new-appointment.php script, where the 'delid' parameter is improperly sanitized before being incorporated into SQL queries. An attacker can remotely send crafted requests to manipulate the SQL statement, potentially extracting, modifying, or deleting sensitive data stored in the backend database. The vulnerability does not require authentication or user interaction, which increases its risk profile. The CVSS 4.0 base score is 6.9 (medium), reflecting the network attack vector, low complexity, and no privileges or user interaction needed. The impact covers confidentiality, integrity, and availability, though with limited scope since it affects only this specific application and version. No official patch is currently available, and while no active exploitation has been reported, a public exploit exists, making it a credible threat. The vulnerability is typical of insufficient input validation and lack of prepared statements in PHP applications, a common security oversight in web-based management systems.

For European organizations, particularly small and medium enterprises in the beauty and wellness sector using PHPGurukul Beauty Parlour Management System 1.1, this vulnerability poses a significant risk. Exploitation could lead to unauthorized disclosure of customer data, appointment details, and business records, impacting confidentiality. Data integrity could be compromised by unauthorized modification or deletion of appointments or customer information, disrupting business operations. Availability might also be affected if attackers manipulate the database to cause application failures or denial of service. Given the remote exploitability without authentication, attackers could target multiple organizations en masse. The reputational damage and potential regulatory consequences under GDPR for data breaches further amplify the impact. Although the product is niche, the presence of a public exploit increases the likelihood of opportunistic attacks against vulnerable installations in Europe.

1. Immediately restrict access to the /admin/new-appointment.php page using network-level controls such as IP whitelisting or VPN access to limit exposure. 2. Implement input validation and sanitization on the 'delid' parameter to ensure only expected numeric or safe values are accepted. 3. Refactor the application code to use parameterized queries or prepared statements to prevent SQL injection. 4. Monitor web server and application logs for suspicious requests targeting the 'delid' parameter or unusual database errors. 5. If possible, upgrade to a patched version of the software once available or consider alternative management systems with better security track records. 6. Conduct security awareness training for administrators to recognize and report suspicious activity. 7. Regularly back up the database and test restoration procedures to mitigate data loss from potential attacks. 8. Employ web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting this endpoint.
