Campcodes Online Beauty Parlor Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes Online Beauty Parlor Management System version 1.0. The issue arises in the file '/admin/search-appointment.php', where the 'searchdata' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without requiring authentication.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, where attackers can read, modify, or delete data. Additionally, it could lead to unauthorized access to sensitive information and disrupt normal service operations.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/search-appointment.php' with a crafted 'searchdata' parameter that includes malicious SQL payloads. Two types of payloads can be used: a time-based blind SQL injection payload that exploits the database's SLEEP function, and a UNION-based SQL injection payload that extracts data by appending a UNION SELECT statement to the original SQL query.

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.
