CWE ID Description
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 is a SQL injection vulnerability in SourceCodester Simple Doctors Appointment System 1.0. The flaw exists in the /admin/ajax.php file when handling the 'ID' parameter for deleting appointments. Attackers can inject malicious SQL code through this parameter without authentication. The exploit allows unauthorized database access, data manipulation, or deletion.

Detection Guidance

To detect this SQL injection vulnerability, check if the /admin/ajax.php?action=delete_appointment endpoint exists and if the 'id' parameter is vulnerable. Use tools like SQLmap to test for SQL injection by sending payloads such as 'id=1' AND 1=1-- or 'id=1' AND 1=2--. Monitor database logs for unusual queries or errors.

Impact Analysis

This vulnerability can lead to unauthorized access to sensitive data like patient records, modification or deletion of appointments, and potential full system compromise. Attackers could steal confidential information, disrupt services, or gain administrative control of the application.

Compliance Impact

This vulnerability likely violates GDPR and HIPAA requirements for protecting personal and health data. It could result in unauthorized data exposure, breaches of confidentiality, and failure to implement adequate security controls, potentially leading to legal penalties and regulatory fines.

Mitigation Strategies

Immediately apply input validation and strict filtering on the 'id' parameter. Replace direct SQL queries with prepared statements using parameter binding. Restrict database user permissions to the minimum required. Conduct a security audit to identify other potential vulnerabilities.
