Codeprojects Online Restaurant Management System SQL Injection Vulnerability in Payment Processing

A critical SQL injection vulnerability has been identified in Codeprojects Online Restaurant Management System version 1.0. The issue arises in the file '/payment_save.php', where the 'mode' parameter is manipulated, leading to unauthorized SQL query modifications. This vulnerability can be exploited remotely, without any authentication, allowing attackers to inject malicious SQL and potentially access or manipulate database information.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, leading to unauthorized database access, data manipulation, and in some cases, execution of administrative operations on the database. 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 the '/payment_save.php' file with a crafted 'mode' parameter. This can be done using tools like sqlmap, which automate the process of 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.
