CVE-2025-3341: Online Restaurant Management SQL Injection

CVE-2025-3341 Overview

A critical SQL injection vulnerability has been identified in codeprojects Online Restaurant Management System version 1.0. The vulnerability exists in the /admin/reservation_view.php file where the ID parameter is not properly sanitized before being used in SQL queries. This flaw allows remote attackers to manipulate database queries through crafted input, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially compromise the entire database server through network-based attacks without authentication.

Technical Details for CVE-2025-3341

Vulnerability Analysis

This SQL injection vulnerability (classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command and CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the reservation management functionality of the application. The vulnerable endpoint /admin/reservation_view.php accepts an ID parameter that is directly incorporated into SQL queries without proper validation or sanitization. This allows attackers to inject arbitrary SQL commands that the database server executes with the same privileges as the application.

The vulnerability is particularly concerning because it can be exploited remotely over the network, requires no user interaction, and does not require prior authentication. Successful exploitation could allow attackers to bypass authentication mechanisms, access sensitive customer and business data, modify reservation records, or potentially escalate to full database compromise.

Root Cause

The root cause of this vulnerability is improper input validation in the reservation_view.php file. The application fails to implement parameterized queries or prepared statements when handling the ID parameter. Instead, user-supplied input is directly concatenated into SQL query strings, creating a classic SQL injection attack surface.

Attack Vector

The attack can be initiated remotely over the network. An attacker can craft malicious HTTP requests to the /admin/reservation_view.php endpoint with specially constructed ID parameter values containing SQL syntax. These malicious payloads can modify the intended SQL query logic to extract data from the database, bypass authentication checks, or execute administrative database operations.

The vulnerability allows for various SQL injection techniques including UNION-based injection for data extraction, boolean-based blind injection for inference attacks, and potentially time-based blind injection for scenarios where direct output is not visible. Since the exploit has been publicly disclosed, organizations running this software should consider themselves at elevated risk.

Detection Methods for CVE-2025-3341

Indicators of Compromise

• Unusual SQL error messages in application logs or web server error logs related to /admin/reservation_view.php
• HTTP requests to /admin/reservation_view.php containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences (--, /*)
• Anomalous database query patterns or execution times associated with reservation view operations
• Unexpected data exfiltration attempts or database enumeration activity

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the ID parameter
• Enable database query logging and monitor for suspicious query structures originating from the reservation management module
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns
• Monitor HTTP access logs for requests containing encoded or obfuscated SQL injection payloads

Monitoring Recommendations

• Configure alerting for any access to /admin/reservation_view.php with abnormal parameter lengths or special characters
• Implement database activity monitoring to detect unauthorized data access or schema enumeration attempts
• Review web server access logs regularly for patterns indicative of automated SQL injection scanning tools
• Enable verbose database logging temporarily to capture the full context of queries during incident investigation

How to Mitigate CVE-2025-3341

Immediate Actions Required

• Restrict network access to the administrative interface at /admin/ using IP whitelisting or VPN requirements
• Implement a web application firewall with SQL injection detection rules as a temporary protective measure
• Consider taking the vulnerable application offline until a patch is available or input validation is implemented
• Back up the database and review access logs for any signs of prior exploitation

Patch Information

No official vendor patch has been released at the time of this publication. Organizations should monitor the GitHub Issue on CVE and VulDB for updates regarding security fixes. In the absence of an official patch, implementing manual code fixes or alternative mitigations is strongly recommended.

Workarounds

• Implement input validation on the ID parameter to accept only numeric values before processing
• Refactor the vulnerable code to use prepared statements or parameterized queries for all database operations
• Deploy a reverse proxy with SQL injection filtering capabilities in front of the application
• Restrict database user privileges to the minimum required for application functionality, limiting potential damage from successful exploitation

# Example: Basic .htaccess rule to restrict admin access by IP
# Add to /admin/.htaccess
<RequireAll>
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
</RequireAll>
