SourceCodester Medical Center Portal Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in SourceCodester Medical Center Portal Management System version 1.0. The issue resides in the file '/emp_edit1.php', where insufficient input validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, which could be used to access, modify, or delete database information. Additionally, it could lead to unauthorized access to sensitive data and disrupt normal service operations.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/medic/pages/emp_edit1.php' with an injected 'id' parameter. This can be done using tools like sqlmap, which can automate the exploitation of SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
