CVE-2021-27320 Scanner

The Doctor Appointment System is a comprehensive solution designed for healthcare providers to manage patient appointments efficiently. It is a web-based platform that allows patients to book, modify, or cancel their appointments online, significantly reducing the administrative burden on staff and improving the patient experience. This system is crucial for clinics and hospitals looking to optimize their operations and provide seamless healthcare services. By facilitating better management of appointment schedules, the Doctor Appointment System helps in reducing waiting times and enhancing patient satisfaction. It is widely adopted in the healthcare industry for its effectiveness in streamlining the appointment booking process.

The vulnerability stems from improper sanitization of user input in the firstname field of the contact form. By injecting malicious SQL code into this parameter, attackers can manipulate the backend database operations. The lack of adequate input validation enables the execution of unintended SQL commands, allowing information retrieval or database manipulation without proper authorization. This flaw highlights critical security weaknesses in handling user inputs and emphasizes the need for implementing robust data validation and sanitization practices in web applications.

Exploiting this SQL Injection vulnerability could lead to severe consequences, including unauthorized access to patient records, disclosure of sensitive information, and potential data corruption or loss. It undermines the security and privacy of the healthcare system, potentially leading to trust erosion among patients and legal implications for the healthcare provider. Additionally, it could enable attackers to launch further attacks against the system or its users, escalating the overall impact.
