CVE-2025-3332: Restaurant Management System SQL Injection

CVE-2025-3332 Overview

A critical SQL injection vulnerability has been discovered in codeprojects Online Restaurant Management System version 1.0. The vulnerability exists in the /admin/menu_save.php file, where improper handling of the menu parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially allowing attackers to manipulate database contents, extract sensitive information, or bypass authentication mechanisms.

Critical Impact

Unauthenticated attackers can remotely exploit this SQL injection vulnerability to manipulate database queries, potentially leading to data theft, unauthorized access, or complete database compromise.

Affected Products

• Code-projects Online Restaurant Management System 1.0
• WordPress installations using the Online Restaurant Management System plugin

Technical Details for CVE-2025-3332

Vulnerability Analysis

This vulnerability is a classic SQL injection flaw (CWE-89) that also falls under the broader category of injection vulnerabilities (CWE-74). The vulnerable endpoint /admin/menu_save.php fails to properly sanitize user-supplied input in the menu parameter before incorporating it into SQL queries. This allows an attacker to manipulate the query structure by injecting malicious SQL syntax.

The attack requires no authentication and can be launched remotely over the network with low complexity. The vulnerability affects the confidentiality, integrity, and availability of the underlying database, though the impact on each is assessed as limited rather than total.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries or prepared statements in the /admin/menu_save.php file. The application directly concatenates user input from the menu parameter into SQL queries without proper sanitization or escaping, creating a classic SQL injection vector.

Attack Vector

The vulnerability is exploitable over the network without requiring user interaction or authentication. An attacker can craft a malicious HTTP request to the /admin/menu_save.php endpoint, embedding SQL injection payloads within the menu parameter. Upon processing the request, the vulnerable application will execute the injected SQL commands against the database.

The attack mechanism involves manipulating the menu parameter to break out of the intended SQL query context and inject additional SQL statements. Attackers could potentially extract sensitive data, modify database records, delete tables, or in some database configurations, execute system commands.

Detection Methods for CVE-2025-3332

Indicators of Compromise

• Unusual or malformed requests to /admin/menu_save.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords in the menu parameter
• Database error messages in application logs indicating SQL syntax errors or unexpected query behavior
• Unexplained database modifications, new administrative accounts, or data exfiltration attempts
• Web server logs showing suspicious parameter values with encoded SQL injection payloads

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the menu parameter
• Enable detailed logging for all requests to /admin/menu_save.php and monitor for anomalous input patterns
• Deploy database activity monitoring to detect unusual queries or unauthorized data access attempts
• Use intrusion detection systems with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor web server access logs for requests to /admin/menu_save.php with suspicious query parameters
• Set up alerts for database errors related to SQL syntax that may indicate injection attempts
• Track database query patterns for anomalies such as UNION-based attacks or time-based blind SQL injection indicators
• Review authentication logs for any unauthorized admin access that could result from successful exploitation

How to Mitigate CVE-2025-3332

Immediate Actions Required

• Restrict network access to the /admin/menu_save.php endpoint using firewall rules or .htaccess configurations
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules enabled
• Consider temporarily disabling the Online Restaurant Management System until a patch is available
• Review and audit all database accounts used by the application for excessive privileges

Patch Information

As of the last update on 2025-04-07, no official patch has been released by the vendor. Organizations should monitor the VulDB entry and vendor communications for patch availability. In the absence of an official fix, implementing the workarounds below is strongly recommended.

Workarounds

• Implement input validation at the web server level using ModSecurity or similar WAF rules to filter SQL injection patterns
• Restrict access to admin endpoints using IP allowlisting or VPN-only access
• Add application-level input sanitization for the menu parameter by escaping special characters
• Consider code modification to implement prepared statements if source code access is available
