Code-Projects Currency Exchange System SQL Injection Vulnerability in edit.php

A SQL injection vulnerability has been identified in Code-Projects Currency Exchange System version 1.0. The issue arises in the file edit.php, where user-supplied input in the ID parameter is not properly sanitized before being incorporated into SQL queries. This flaw allows remote attackers to inject malicious SQL, potentially leading to unauthorized data access, data manipulation, or even system control.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can manipulate database queries. This could result in unauthorized access to database information, such as user data or application records, and could also allow for modification or deletion of database entries. In severe cases, such exploitation could lead to gaining control over the underlying system.

Reproduction

The vulnerability can be reproduced by sending a GET request to edit.php with a crafted ID parameter that includes SQL injection payloads. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding for database queries, ensuring that user input is properly validated and sanitized. Additionally, minimizing database user permissions and conducting regular security audits can help prevent similar vulnerabilities.
