itsourcecode Courier Management System SQL Injection Vulnerability in edit_user.php

A SQL injection vulnerability exists in the itsourcecode Courier Management System version 1.0, specifically within the edit_user.php file. The issue arises from an unknown function that allows for the manipulation of the 'id' parameter, enabling attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and other serious security risks.

Impact

Exploitation of this vulnerability allows for SQL injection, which could be used to access or manipulate the database, leak sensitive information, alter data, gain extensive control over the system, or disrupt services.

Reproduction

To reproduce this vulnerability, log into the application with valid credentials and navigate to the edit_user.php file. Once there, manipulate the 'id' parameter in the URL to inject SQL payloads. This can be done using boolean-based blind, time-based blind, or UNION query injection techniques.

Remediation

To address this vulnerability, 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.
