Campcodes Sales and Inventory System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. The issue resides in the file '/pages/creditor_add.php', where the 'last' parameter is improperly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data manipulation, and disruption of service.

Impact

Reproduction

To reproduce this vulnerability, send a POST request to '/pages/creditor_add.php' with crafted payloads in the 'last' parameter that exploit SQL injection vulnerabilities. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection flaws.

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.
