itsourcecode Online Doctor Appointment System SQL Injection Vulnerability in Patient Action File

A SQL injection vulnerability has been identified in the Online Doctor Appointment System version 1.0, specifically within the admin/patient_action.php file. The issue arises from inadequate validation of the patient_id parameter, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, which could be used to access, modify, or delete database information. Such actions could disrupt service and compromise system security.

Reproduction

The vulnerability can be reproduced by sending a POST request to the admin/patient_action.php file with a crafted patient_id parameter that includes malicious SQL code. This can be done using tools like sqlmap, which can automate the exploitation of SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to implement input validation and sanitization for the patient_id parameter, use prepared statements to prevent SQL injection, and conduct regular security audits to identify and fix vulnerabilities.
