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.
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.

Executive Summary

This vulnerability is a SQL injection flaw in SourceCodester Simple Doctors Appointment System 1.0. It exists in the /admin/ajax.php file when the action=set_appointment parameter is used. The weakness allows attackers to inject malicious SQL queries through the ID argument without authentication. This occurs due to improper input validation.

Detection Guidance

To detect this SQL injection vulnerability, you can use tools like sqlmap to test the affected endpoint. Example command: sqlmap -u 'http://target.com/doctors/admin/ajax.php?action=set_appointment&id=1' --batch. Alternatively, manually test with payloads like ' OR 1=1 -- or ' OR '1'='1' to check for blind or time-based SQL injection.

Impact Analysis

This vulnerability can lead to unauthorized database access, data manipulation, sensitive information leakage, system compromise, or service disruption. Attackers can use techniques like boolean-based blind or time-based blind SQL injection to exploit it. Tools like sqlmap can automate exploitation attempts.

Compliance Impact

This SQL injection vulnerability could lead to unauthorized database access and sensitive information leakage, which directly violates GDPR's data protection requirements and HIPAA's safeguards for protected health information. Unauthorized access to patient or appointment data would result in non-compliance with these regulations.

Mitigation Strategies

Immediately update the application to use prepared statements with parameterized queries for all database interactions. Implement strict input validation to sanitize user-supplied data, especially for the 'id' parameter. Restrict database user permissions to the minimum required and conduct a security audit to identify other potential vulnerabilities.
