Executive Summary

CVE-2026-2848 is a critical SQL injection vulnerability found in SourceCodester Simple Responsive Tourism Website version 1.0. The flaw exists in the file `/classes/Master.php` within the Registration component, specifically when handling the `username` parameter during the registration process (`f=register`).

Improper sanitization or neutralization of this externally supplied input allows an attacker to manipulate SQL commands, leading to SQL injection (CWE-89). This means an attacker can inject malicious SQL code into the database query, potentially compromising the system.

The attack can be launched remotely without any authentication, making exploitation straightforward and accessible. Proof-of-concept exploits demonstrate multiple SQL injection techniques such as Boolean-based blind, error-based, and time-based blind SQL injection.

Mitigation Strategies

[{'type': 'paragraph', 'content': 'Immediate mitigation steps include replacing the affected product with an alternative solution if possible.'}, {'type': 'paragraph', 'content': 'If replacement is not feasible, implement prepared statements with parameter binding to separate SQL code from user input, preventing injection.'}, {'type': 'paragraph', 'content': "Enforce strict input validation and filtering on the 'username' parameter to ensure it conforms to expected formats."}, {'type': 'paragraph', 'content': "Minimize database user privileges by avoiding the use of high-privilege accounts (such as root or admin) for the application's database connections."}, {'type': 'paragraph', 'content': 'Conduct regular security audits of the code and systems to detect and fix vulnerabilities promptly.'}] [1, 3, 2]
