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

A SQL injection vulnerability has been identified in Code-Projects Simple Laundry System version 1.0. The issue resides in the delmemberinfo.php file, specifically within the Parameter Handler component. The vulnerability allows remote attackers to inject malicious SQL queries through the userid parameter, exploiting inadequate input validation. This exploitation could lead to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could result in unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a request to the delmemberinfo.php file with a crafted userid parameter that includes malicious SQL code. 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. 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.
