SQL Injection in Yash Pokharna Restaurant Management System

Impact Analysis

This SQL injection vulnerability can have significant impacts including unauthorized access to sensitive data stored in the database, such as user credentials and personal information.

Attackers can exploit this flaw to manipulate database queries, potentially leading to data leakage, data modification, or even complete compromise of the application’s backend database.

Since the vulnerability affects authentication and password reset functions, it could allow attackers to bypass security controls, reset passwords of other users, or escalate privileges.

Detection Guidance

This SQL injection vulnerability in the forgotpassword.php file can be detected by testing the POST parameter 'email' for SQL injection flaws.

A practical approach is to use sqlmap, an automated tool for detecting and exploiting SQL injection vulnerabilities, targeting the forgotpassword.php endpoint with a POST request.

• Example sqlmap command: sqlmap -u "http://targetsite/forgotpassword.php" --data="[email protected]" --risk=3 --level=5 --batch
• This command tests the 'email' POST parameter for SQL injection by sending crafted payloads and analyzing responses.

Additionally, monitoring network traffic for suspicious POST requests to forgotpassword.php with unusual or malformed 'email' parameters may help detect exploitation attempts.

Mitigation Strategies

Immediate mitigation involves reviewing and refactoring the vulnerable code in forgotpassword.php and related authentication files to prevent SQL injection.

• Replace all raw SQL queries that concatenate user input directly with prepared statements using bound parameters.
• Ensure all user-controlled inputs, especially the 'email' parameter in password reset functions, are properly validated and sanitized.
• Review other related files such as updatepassword.php, login_register.php, and admin.php for similar vulnerabilities and apply the same secure coding practices.

Since the exploit is publicly available and the project has not responded to the issue report, applying these code changes promptly is critical to reduce risk.

Compliance Impact

The vulnerability is a SQL injection in the password reset functionality that allows remote attackers to manipulate the email parameter and potentially access or alter sensitive data in the database.

Such unauthorized access or manipulation of personal data can lead to violations of data protection regulations like GDPR and HIPAA, which require strict controls to protect personal and sensitive information.

Because the vulnerability allows attackers to retrieve or modify user data without authorization, it undermines confidentiality, integrity, and availability of data, which are core principles in these standards.

Therefore, exploitation of this vulnerability could result in non-compliance with these regulations, potentially leading to legal and financial consequences for organizations using the affected system.

Executive Summary

This vulnerability is a SQL injection issue found in the restaurent-management-system, specifically in the forgotpassword.php file. The email parameter in a POST request is directly concatenated into SQL queries without proper validation or escaping, allowing an attacker to manipulate the SQL commands executed by the database.

Such manipulation enables blind SQL injection attacks, where attackers can retrieve sensitive information like the database name or perform other unauthorized database operations remotely.

The vulnerability is confirmed by testing tools like sqlmap and affects multiple authentication-related files in the system due to similar insecure coding patterns.
