CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

This vulnerability is a SQL Injection found in the checkUser.php file of the Simple Flight Ticket Booking System version 1.0 by Code-Projects. It occurs because the Username parameter is not properly sanitized before being used in SQL queries. This allows an attacker to inject malicious SQL code remotely, potentially manipulating the database queries executed by the system.

Impact Analysis

Exploiting this SQL Injection vulnerability can allow attackers to bypass authentication, access sensitive data stored in the database, or modify database records. This can lead to unauthorized access to user accounts, data breaches, and potential manipulation or destruction of critical information within the flight ticket booking system.

Detection Guidance

This SQL Injection vulnerability in checkUser.php can be detected by testing the Username POST parameter with crafted inputs that manipulate SQL queries.

One common detection method is to use time-based SQL injection payloads that cause a delayed response if the vulnerability exists.

  • Send a POST request to the vulnerable endpoint with a payload like: Username=anything' OR SLEEP(5)--
  • Example curl command to test the delay-based injection: curl -X POST -d "Username=admin' OR SLEEP(5)-- &Password=any" http://targetsite/checkUser.php

If the response time is significantly delayed, it indicates the presence of the SQL injection vulnerability.

Mitigation Strategies

To mitigate this SQL Injection vulnerability, immediate steps include sanitizing and validating all user inputs, especially the Username parameter.

Implement prepared statements or parameterized queries to prevent direct concatenation of user input into SQL commands.

If possible, apply any available patches or updates from the vendor for the Simple Flight Ticket Booking System.

Additionally, consider implementing web application firewalls (WAF) rules to detect and block SQL injection attempts.

Compliance Impact

The SQL Injection vulnerability in the Simple Flight Ticket Booking System allows attackers to manipulate SQL queries, potentially bypass authentication and access or alter sensitive database data.

Such unauthorized access and manipulation of sensitive data can lead to violations of data protection regulations like GDPR and HIPAA, which require safeguarding personal and sensitive information against unauthorized access and breaches.

Therefore, this vulnerability poses a risk to compliance with these standards by exposing sensitive user data to potential compromise.
