Code-Projects Simple Scheduling System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Simple Scheduling System version 1.0. The issue resides in the '/schedulingsystem/addtime.php' file, where the 'starttime' and 'endtime' parameters are manipulated to inject malicious SQL queries. This vulnerability allows remote attackers to gain unauthorized access to the database, modify or delete data, and access sensitive information. The vulnerability arises from inadequate input validation, enabling attackers to manipulate SQL queries and execute unauthorized operations.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of database contents, and potential execution of administrative operations on the database server. This poses a significant risk to the application's data integrity and security.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/schedulingsystem/addtime.php' with the 'starttime' parameter crafted to include malicious SQL payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, 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 enhance the application's security.
