SQL Injection in SourceCodester Online Book Store System

Compliance Impact

The SQL injection vulnerability in the administrative login page allows attackers to bypass authentication and gain unauthorized access to sensitive administrative functions and data. This unauthorized access can lead to exposure or manipulation of personal and sensitive information, which may violate data protection requirements under regulations such as GDPR and HIPAA.

Specifically, the compromise of administrative controls and data integrity can result in non-compliance with standards that mandate strict access controls, data confidentiality, and integrity protections. Organizations using the affected system may face increased risk of data breaches, regulatory penalties, and loss of trust if this vulnerability is exploited.

Mitigation measures such as using prepared statements, input validation, and secure coding practices are essential to maintain compliance with these regulations by preventing unauthorized data access.

Executive Summary

This vulnerability is a SQL Injection flaw found in the admin login page of the SourceCodester Online Book Store System 1.0, specifically in the admin/login.php file. It occurs because the Username input is not properly sanitized or parameterized before being used in SQL queries. An attacker can manipulate the Username argument with malicious SQL code to bypass authentication checks.

By injecting SQL code such as ' OR 1=1 -- -, an attacker can trick the system into granting access without valid credentials, effectively bypassing the login process.

Detection Guidance

This vulnerability can be detected by testing the administrative login page for SQL injection flaws. One common method is to input a malicious payload such as ' OR 1=1 -- - into the username field and observe if authentication is bypassed.

Network or system detection can involve monitoring for unusual login attempts or suspicious SQL injection patterns targeting the admin/login.php endpoint.

• Use curl or similar tools to send a crafted login request with a payload like: curl -d "Username=' OR 1=1 -- -&Password=anything" http://targetsite/admin/login.php
• Check web server logs for repeated failed or suspicious login attempts containing SQL injection payloads.

Mitigation Strategies

Immediate mitigation steps include implementing prepared statements and parameterized queries to prevent SQL injection.

Strict input validation should be enforced on all user inputs, especially the Username field in admin/login.php.

Conduct secure code reviews to identify and fix injection vulnerabilities.

Additionally, enforce modern password hashing and consider restricting access to the administrative login page.
