Code-Projects Simple Laundry System SQL Injection Vulnerability in delstaffinfo.php

A SQL injection vulnerability has been identified in Code-Projects Simple Laundry System version 1.0. The issue arises in the delstaffinfo.php file within the Parameter Handler component, where insufficient validation of the userid parameter allows for the injection of 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 attackers to inject malicious SQL queries, bypassing authentication and authorization. This could result in unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. The vulnerability poses a significant risk to the application's data integrity and security.

Reproduction

The vulnerability can be reproduced by sending a request to the delstaffinfo.php file with a crafted userid parameter that includes malicious SQL payloads. This can be done using a tool 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.
