CVE-2025-3338: Online Restaurant Management SQL Injection

CVE-2025-3338 Overview

A SQL injection vulnerability has been discovered in codeprojects Online Restaurant Management System version 1.0. The vulnerability exists in the /admin/user_save.php file, where the Name parameter is susceptible to SQL injection attacks due to improper input validation and sanitization. This flaw allows remote attackers to manipulate SQL queries by injecting malicious input through the affected parameter, potentially compromising the underlying database and any sensitive information it contains.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially execute unauthorized administrative operations on the Online Restaurant Management System. Other parameters in the same file may also be vulnerable.

Affected Products

• codeprojects Online Restaurant Management System 1.0
• /admin/user_save.php endpoint
• Name parameter and potentially other parameters

Technical Details for CVE-2025-3338

Vulnerability Analysis

This SQL injection vulnerability in the Online Restaurant Management System stems from inadequate input validation in the /admin/user_save.php file. When user-supplied data is passed through the Name parameter, the application fails to properly sanitize or parameterize the input before incorporating it into SQL queries. This allows attackers to inject arbitrary SQL commands that are then executed by the database server.

The exploit has been publicly disclosed, increasing the risk of active exploitation. The vulnerability can be exploited remotely without authentication, as the affected endpoint does not appear to implement proper access controls in combination with the injection flaw. The advisory notes that other parameters within the same file may also be vulnerable to similar attacks.

Root Cause

The root cause of this vulnerability is the lack of proper input sanitization and the use of unsanitized user input directly in SQL queries. The application likely constructs SQL statements through string concatenation rather than using parameterized queries or prepared statements. This classic web application security flaw (CWE-89: SQL Injection, CWE-74: Improper Neutralization of Special Elements) allows attackers to escape the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack can be launched remotely over the network. An attacker would craft a malicious HTTP request to the /admin/user_save.php endpoint, including SQL injection payloads in the Name parameter. Since no authentication appears to be required for exploitation, the attack surface is accessible to any remote attacker who can reach the web application.

The vulnerability allows for injection of SQL syntax that can modify query logic, extract data through UNION-based or blind injection techniques, or potentially execute database administrative commands depending on the database configuration and privileges.

Detection Methods for CVE-2025-3338

Indicators of Compromise

• Unusual requests to /admin/user_save.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords (SELECT, UNION, DROP, etc.)
• Database error messages in application logs indicating malformed SQL queries
• Unexpected database queries or data modifications in database audit logs
• Web server access logs showing suspicious payloads in POST/GET parameters targeting the Name field

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /admin/user_save.php endpoint
• Implement application-level logging to capture all input to the Name parameter and other user-supplied fields
• Enable database query logging to identify anomalous or injected SQL statements
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor web server access logs for requests to /admin/user_save.php with encoded or obfuscated SQL payloads
• Set up alerts for database errors that may indicate injection attempts
• Review database audit logs for unauthorized data access or modifications
• Implement real-time monitoring for unusual database activity patterns

How to Mitigate CVE-2025-3338

Immediate Actions Required

• Restrict access to the /admin/user_save.php endpoint through network-level controls or authentication requirements
• Deploy WAF rules to filter SQL injection payloads targeting the affected parameters
• Review and audit all user input handling in the application, particularly in administrative functions
• Consider taking the affected functionality offline until a proper fix can be implemented

Patch Information

As of the last NVD update on 2025-04-29, no official vendor patch has been released for this vulnerability. Organizations using the Online Restaurant Management System should contact codeprojects for remediation guidance or consider implementing the workarounds described below. For additional technical details, refer to the GitHub Issue CVE-52 and VulDB entry #303552.

Workarounds

• Implement prepared statements or parameterized queries for all database interactions in the affected file
• Add strict input validation to sanitize the Name parameter and any other user-supplied inputs
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Restrict network access to the administrative interface to trusted IP addresses only
• Enable the principle of least privilege for database accounts used by the application

# Example: Restrict access to admin directory using Apache .htaccess
# Place this file in the /admin/ directory
<Files "user_save.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    # Replace with your trusted admin network range
</Files>
