Code-Projects Simple Pizza Ordering System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Simple Pizza Ordering System version 1.0. The issue resides in the '/adduser-exec.php' file, where the 'username' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows unauthorized database access, manipulation of database contents, and potential leakage of sensitive information. It poses a significant risk to the overall security of the system and its data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'adduser-exec.php' with a crafted 'username' parameter that includes malicious SQL payloads. This injection takes advantage of time-based blind SQL injection techniques, such as using the SQL 'SLEEP' function to demonstrate the vulnerability.

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 are also advisable.
