CVE-2025-4936: Online Food Ordering System SQLi Flaw

CVE-2025-4936 Overview

A SQL injection vulnerability has been discovered in Projectworlds Online Food Ordering System version 1.0. This vulnerability exists in the /admin-page.php file, where the 1_price parameter is improperly validated, allowing attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially enabling attackers to access, modify, or delete sensitive data within the application's database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to manipulate database queries, potentially leading to unauthorized data access, data manipulation, and complete database compromise.

Technical Details for CVE-2025-4936

Vulnerability Analysis

This SQL injection vulnerability stems from improper input validation in the administrative interface of the Online Food Ordering System. The 1_price parameter in /admin-page.php is directly incorporated into database queries without proper sanitization or parameterization. When processing price-related data, the application fails to properly escape or validate user input, creating a direct injection point into the backend SQL database.

The vulnerability allows unauthenticated remote attackers to craft malicious requests that can manipulate the underlying database queries. This can result in unauthorized data extraction, modification of existing records, or deletion of critical application data. Given the nature of food ordering systems, compromised data could include customer personal information, payment details, and order histories.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and the use of unsanitized user input in SQL query construction. The application directly concatenates user-supplied data from the 1_price parameter into SQL statements rather than using parameterized queries or prepared statements. This fundamental coding flaw violates secure development practices and creates a classic SQL injection attack surface.

Attack Vector

The attack can be launched remotely over the network without requiring any authentication or user interaction. An attacker can craft HTTP requests to the /admin-page.php endpoint with malicious SQL payloads in the 1_price parameter. The exploit has been publicly disclosed, increasing the risk of widespread exploitation.

The attacker sends specially crafted input through the 1_price parameter that breaks out of the intended SQL query structure. By injecting SQL syntax such as single quotes, UNION statements, or conditional logic, the attacker can extract sensitive information from the database, bypass authentication mechanisms, or execute administrative operations on the database server.

Detection Methods for CVE-2025-4936

Indicators of Compromise

• Unusual SQL error messages in application logs referencing the 1_price parameter or /admin-page.php
• Web server logs showing requests to /admin-page.php containing SQL keywords (UNION, SELECT, INSERT, DELETE, OR, AND) in parameter values
• Database logs indicating unexpected query patterns or unauthorized data access attempts
• Evidence of data exfiltration or unexpected changes to database records

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the 1_price parameter
• Configure intrusion detection systems to alert on HTTP requests containing SQL metacharacters in POST or GET parameters to /admin-page.php
• Enable detailed logging on web servers and databases to capture suspicious query attempts
• Deploy application-level monitoring to track anomalous database query behavior

Monitoring Recommendations

• Monitor web server access logs for repeated requests to /admin-page.php with unusual parameter values
• Set up alerts for database errors related to malformed SQL queries
• Implement real-time log analysis to detect SQL injection attack patterns
• Review database audit logs for unauthorized read or write operations

How to Mitigate CVE-2025-4936

Immediate Actions Required

• Remove or restrict access to /admin-page.php until a patch is available or input validation is implemented
• Implement Web Application Firewall rules to block SQL injection attempts targeting this endpoint
• Review and audit all database access points in the application for similar vulnerabilities
• Consider taking the application offline if sensitive data is at risk and no immediate fix is available

Patch Information

As of the last update on 2025-06-05, no official vendor patch has been released for this vulnerability. Organizations using Projectworlds Online Food Ordering System 1.0 should monitor vendor communications for security updates. Additional technical details can be found at the GitHub CVE Issue Discussion and VulDB #309498.

Workarounds

• Implement parameterized queries or prepared statements for all database interactions involving the 1_price parameter
• Deploy input validation that rejects SQL metacharacters and enforces expected data formats for price fields
• Restrict network access to administrative pages like /admin-page.php using IP allowlisting or VPN requirements
• Apply the principle of least privilege to database accounts used by the application to limit potential damage from successful exploitation

# Example: Restrict access to admin-page.php via Apache .htaccess
<Files "admin-page.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    # Replace with your trusted IP range
</Files>
