CWE ID Description
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability is a SQL injection flaw in the Online-Appointment-Booking-System. It exists in the Admin/deleteclinic.php file where the cid/did arguments are not properly sanitized. Attackers can manipulate these inputs to execute arbitrary SQL commands on the database.

Detection Guidance

To detect SQL injection vulnerabilities in the Admin/deleteclinic.php component, inspect HTTP requests to the cid/did parameters for unusual input patterns like single quotes, semicolons, or SQL keywords (e.g., UNION, SELECT). Use tools like SQLmap to test for injection points by sending crafted payloads to these parameters.

If exploited, this vulnerability could allow attackers to read, modify, or delete sensitive data in the database. This includes patient records, appointment details, or administrative credentials. The attack can be performed remotely without authentication.

Compliance Impact

This vulnerability likely violates GDPR and HIPAA requirements for data protection and security. It could lead to unauthorized access to personal health information, resulting in legal penalties, fines, and reputational damage for organizations using the affected system.

Mitigation Strategies

Immediately restrict access to the Admin/deleteclinic.php endpoint. Apply input validation to sanitize cid/did parameters, using prepared statements or parameterized queries. Monitor database logs for suspicious queries. Consider disabling the endpoint until a patch is released.
