CVE-2025-6483: Simple Pizza Ordering System SQLi Flaw

CVE-2025-6483 Overview

A critical SQL injection vulnerability has been identified in code-projects Simple Pizza Ordering System version 1.0. The vulnerability exists in the /edituser.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive user data, modify database records, or potentially gain further access to the underlying system through database manipulation techniques.

Technical Details for CVE-2025-6483

Vulnerability Analysis

This SQL injection vulnerability affects the /edituser.php endpoint in the Simple Pizza Ordering System. The application fails to properly sanitize user-supplied input in the ID parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL commands that are then executed by the database server.

The vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The exploit has been publicly disclosed, increasing the risk of active exploitation in the wild.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries or prepared statements in the /edituser.php file. When the application processes the ID parameter, it directly concatenates user input into SQL query strings without sanitization, escaping, or the use of parameterized queries. This allows specially crafted input containing SQL syntax to alter the intended query logic.

Attack Vector

The attack can be launched remotely over the network without requiring authentication. An attacker can craft malicious HTTP requests to the /edituser.php endpoint with specially constructed ID parameter values containing SQL injection payloads. These payloads can be designed to:

• Extract sensitive data from the database using UNION-based or blind SQL injection techniques
• Modify or delete existing database records
• Bypass authentication mechanisms
• Potentially execute operating system commands if database permissions allow

The vulnerability is exploitable through standard HTTP requests, making it accessible to any attacker with network access to the vulnerable application.

Detection Methods for CVE-2025-6483

Indicators of Compromise

• Unusual SQL error messages in application logs or web responses from /edituser.php
• Unexpected database queries containing SQL keywords like UNION, SELECT, OR 1=1, or comment sequences (--, /**/)
• Anomalous access patterns to the /edituser.php endpoint with unusual ID parameter values
• Database logs showing unauthorized data extraction or modification attempts

Detection Strategies

• Deploy Web Application Firewalls (WAF) with SQL injection detection rules to monitor and block malicious requests to /edituser.php
• Implement database activity monitoring to detect anomalous queries or unauthorized data access patterns
• Review web server access logs for requests containing SQL injection patterns in the ID parameter
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable verbose logging on the web application to capture all requests to /edituser.php including full parameter values
• Configure database audit logging to track all queries executed against user-related tables
• Set up alerts for HTTP requests containing common SQL injection characters and keywords (', ", ;, --, UNION, SELECT)
• Monitor for unusual spikes in error responses from the application that may indicate exploitation attempts

How to Mitigate CVE-2025-6483

Immediate Actions Required

• Remove or restrict access to the /edituser.php file if the functionality is not critical
• Implement network-level access controls to limit exposure of the vulnerable application
• Deploy a Web Application Firewall with SQL injection protection rules as an interim measure
• Review and audit all database accounts for excessive privileges and apply principle of least privilege

Patch Information

No official vendor patch information is currently available. Organizations using the Simple Pizza Ordering System should monitor the Code Projects Security Overview and the GitHub Issue Discussion on CVE for updates. Additional vulnerability details can be found at VulDB ID #313591.

Workarounds

• Implement server-side input validation to sanitize the ID parameter, ensuring only numeric values are accepted
• Modify the application code to use prepared statements or parameterized queries for all database interactions
• Restrict access to the vulnerable endpoint through IP whitelisting or authentication requirements
• Consider taking the application offline or replacing it with a secure alternative until a proper fix is available

# Example: Apache .htaccess to restrict access to edituser.php
<Files "edituser.php">
    Order deny,allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
