Campcodes Computer Sales and Inventory System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Campcodes Computer Sales and Inventory System version 1.0. The issue arises in the file '/pages/us_edit.php' when the 'id' parameter is manipulated. This vulnerability allows remote attackers to inject malicious SQL queries, potentially leading to unauthorized database access, data modification or deletion, and exposure 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, extract or modify data, and disrupt services.

Reproduction

To reproduce this vulnerability, send a GET request to '/pages/us_edit.php' with the 'action' parameter set to 'edit' and the 'id' parameter set to a value that can be used to manipulate the SQL query. The injection can be verified by using payloads that exploit boolean-based blind, error-based, time-based blind, or UNION-based SQL injection techniques.

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.
