CVE-2025-3330: Online Restaurant Management System SQLi

CVE-2025-3330 Overview

CVE-2025-3330 is a SQL Injection vulnerability affecting Code-projects Online Restaurant Management System version 1.0. The vulnerability exists within the /reservation_save.php file, where improper handling of the first parameter allows attackers to inject malicious SQL queries. This flaw enables remote, unauthenticated attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or further system compromise.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to extract sensitive data, modify database contents, or potentially compromise the underlying server without authentication.

Technical Details for CVE-2025-3330

Vulnerability Analysis

This SQL Injection vulnerability stems from improper input validation in the /reservation_save.php endpoint of the Online Restaurant Management System. The first parameter, likely used for storing customer first name data during reservation creation, fails to properly sanitize user input before incorporating it into SQL queries.

When processing reservation requests, the application constructs SQL statements using user-supplied data without adequate parameterization or input filtering. This allows attackers to inject arbitrary SQL syntax that gets executed by the database server. The vulnerability can be exploited remotely without any prior authentication, making it particularly dangerous for public-facing deployments.

The CVE description notes that other parameters within the same endpoint may also be affected, suggesting a systemic lack of input validation throughout the reservation handling functionality.

Root Cause

The root cause is a classic CWE-89 (SQL Injection) vulnerability combined with CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The application fails to implement prepared statements or parameterized queries when handling user input in the reservation save functionality. Instead, user-supplied values are directly concatenated into SQL query strings, allowing attackers to break out of the intended query structure and inject malicious commands.

Attack Vector

The attack is network-based and can be initiated remotely by any unauthenticated attacker with access to the web application. An attacker would craft a malicious HTTP request to the /reservation_save.php endpoint, embedding SQL injection payloads within the first parameter. Common attack techniques include:

• Union-based injection: Extracting data from other database tables by appending UNION SELECT statements
• Boolean-based blind injection: Inferring database contents through conditional responses
• Time-based blind injection: Using database SLEEP functions to extract data bit by bit
• Error-based injection: Extracting information from verbose database error messages

The attack requires no user interaction and can be automated using tools such as SQLMap. Successful exploitation could lead to complete database compromise, including extraction of customer personal information, payment details, and administrative credentials.

Detection Methods for CVE-2025-3330

Indicators of Compromise

• Unusual or malformed requests to /reservation_save.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
• Web server logs showing requests with encoded SQL payloads in the first parameter
• Database logs indicating query errors or unusual query patterns from the web application
• Unexpected database queries containing UNION, SELECT, DROP, or other suspicious SQL statements

Detection Strategies

• Deploy a Web Application Firewall (WAF) with SQL Injection detection rules to monitor traffic to /reservation_save.php
• Enable detailed logging on the web server and database to capture suspicious query activity
• Implement runtime application self-protection (RASP) to detect SQL injection attempts in real-time
• Use SentinelOne Singularity to monitor for post-exploitation activities following successful SQL injection

Monitoring Recommendations

• Configure alerts for high volumes of requests to the /reservation_save.php endpoint
• Monitor database query logs for syntax errors that may indicate injection attempts
• Set up anomaly detection for unusual data exfiltration patterns from the database
• Review web application logs regularly for requests containing SQL injection patterns

How to Mitigate CVE-2025-3330

Immediate Actions Required

• Restrict network access to the Online Restaurant Management System to trusted IP addresses only
• Consider temporarily disabling the reservation functionality if the system cannot be immediately patched
• Implement a WAF with strict SQL Injection filtering rules as a compensating control
• Review database access logs for evidence of prior exploitation

Patch Information

As of the last update on 2025-04-07, no official vendor patch has been published. The vulnerability has been publicly disclosed, and the exploit details are available. Organizations using Code-projects Online Restaurant Management System should monitor for vendor updates and consider implementing the workarounds below until a patch becomes available. For technical details, refer to the GitHub CVE Issue Discussion and VulDB #303544.

Workarounds

• Implement input validation at the application level to reject requests containing SQL metacharacters in the first parameter and other user inputs
• Deploy a reverse proxy or WAF configured to filter SQL injection payloads before they reach the application
• If source code access is available, modify /reservation_save.php to use prepared statements with parameterized queries
• Consider replacing the vulnerable application with a more secure restaurant management solution
• Isolate the application server and database to limit the impact of successful exploitation
