Description Preview

A critical SQL Injection vulnerability has been identified in SourceCodester Task Reminder System version 1.0. The vulnerability exists in the /admin/reminders/manage_reminder.php file, where improper validation of the 'id' parameter allows attackers to inject and execute malicious SQL commands. This vulnerability can be exploited remotely and could potentially lead to unauthorized access to the database, data theft, data manipulation, or even complete system compromise. The vulnerability has been publicly disclosed and exploit code may be available, increasing the risk for unpatched systems.

Overview

The SQL Injection vulnerability in SourceCodester Task Reminder System 1.0 occurs due to insufficient input validation in the manage_reminder.php file located in the admin/reminders directory. When processing the 'id' parameter, the application fails to properly sanitize or parameterize the user input before incorporating it into SQL queries. This allows an attacker to inject malicious SQL code that can be executed by the database server. Depending on the database configuration and permissions, this vulnerability could allow attackers to:

  • Extract sensitive information from the database
  • Modify database contents
  • Delete data
  • Bypass authentication mechanisms
  • Execute administrative operations on the database
  • In some cases, gain access to the underlying operating system

Remediation

To remediate this vulnerability, system administrators and developers should:

  1. Update to a newer version of Task Reminder System if available.
  2. If no update is available, implement proper input validation and parameterized queries:
    • Replace direct inclusion of user input in SQL queries with prepared statements
    • Use parameterized queries with bound variables
    • Implement input validation to reject potentially malicious input
    • Apply the principle of least privilege for database connections
  3. Consider implementing a Web Application Firewall (WAF) to help detect and block SQL injection attempts.
  4. Conduct a thorough security review of the application to identify and address similar vulnerabilities in other components.
  5. Monitor system logs for suspicious activities that might indicate exploitation attempts.
