itsourcecode Restaurant Management System SQL Injection Vulnerability in User Save PHP File

A critical SQL injection vulnerability has been identified in the itsourcecode Restaurant Management System version 1.0. The issue resides in the '/admin/user_save.php' file, where insufficient input validation of the 'username' and 'name' parameters 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, where attackers can manipulate database queries to gain unauthorized access to the database, modify or delete data, and access sensitive information. This poses a significant risk to the overall security of the system and the integrity of its data.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/admin/user_save.php' file with crafted payloads that exploit the SQL injection flaw. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
