A vulnerability classified as critical was found in code-projects Online Appointment Booking System 1.0. This vulnerability affects unknown code of the file /cancelbookingpatient.php. The manipulation of the argument appointment leads to sql injection. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.
AnalysisAI
CVE-2025-7516 is a critical SQL injection vulnerability in code-projects Online Appointment Booking System version 1.0, affecting the /cancelbookingpatient.php endpoint via the 'appointment' parameter. An unauthenticated remote attacker can exploit this to execute arbitrary SQL queries, potentially leading to unauthorized data access, modification, or deletion of appointment records and sensitive patient information. Public disclosure and proof-of-concept availability indicate active exploitation risk.
Technical ContextAI
The vulnerability stems from improper input validation and parameterization in the appointment cancellation functionality. The /cancelbookingpatient.php file fails to sanitize or use prepared statements for the 'appointment' parameter before incorporating it into SQL queries, enabling classic SQL injection (CWE-74: Improper Neutralization of Special Elements used in an Output ('Injection')). This is a type of second-order or direct injection vulnerability in a PHP-based appointment management system. The affected product is code-projects Online Appointment Booking System 1.0, a web application for managing patient appointment scheduling.
