CVE-2025-3345: Online Restaurant Management SQL Injection

CVE-2025-3345 Overview

A SQL injection vulnerability has been identified in codeprojects Online Restaurant Management System version 1.0. The vulnerability exists in the /admin/combo.php file, where the del parameter is not properly sanitized before being used in SQL queries. This allows remote attackers to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion within the database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, bypass authentication, modify database records, or potentially gain further system access through the compromised web application.

Technical Details for CVE-2025-3345

Vulnerability Analysis

This SQL injection vulnerability occurs in the administrative interface of the Online Restaurant Management System. The /admin/combo.php endpoint accepts a del parameter that is directly incorporated into SQL queries without proper validation or parameterization. When an attacker manipulates this parameter with specially crafted SQL syntax, the malicious input is executed by the database server, allowing unauthorized database operations.

The vulnerability is classified under both 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). The attack requires no authentication and can be exploited remotely over the network with low complexity.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries (prepared statements) in the application code. User-supplied input through the del parameter is directly concatenated into SQL query strings without sanitization, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The attack can be performed remotely over the network without requiring any user interaction or authentication. An attacker can craft malicious HTTP requests to the /admin/combo.php endpoint with SQL injection payloads in the del parameter. This could enable the attacker to:

• Extract sensitive information from the database (customer data, credentials, financial records)
• Modify or delete critical application data
• Bypass authentication mechanisms
• Potentially escalate to command execution if database functions allow

The exploit has been publicly disclosed, increasing the risk of active exploitation against vulnerable installations.

Detection Methods for CVE-2025-3345

Indicators of Compromise

• Suspicious HTTP requests to /admin/combo.php containing SQL syntax characters (single quotes, double dashes, semicolons, UNION keywords)
• Unusual database query patterns or errors in application logs
• Database queries containing unexpected SQL commands like SELECT, UNION, DROP, or INSERT from web application contexts
• Unauthorized data access or unexplained data modifications in the restaurant management system

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the del parameter
• Monitor HTTP access logs for requests to /admin/combo.php with anomalous parameter values
• Enable database query logging and alert on queries containing suspicious SQL syntax originating from the web application
• Implement intrusion detection system (IDS) signatures for common SQL injection attack patterns

Monitoring Recommendations

• Configure real-time alerting for access attempts to /admin/combo.php with unusual parameter lengths or special characters
• Monitor database server logs for failed queries or syntax errors that may indicate exploitation attempts
• Implement application-level logging to capture all input parameters for security review
• Regularly audit database access patterns for anomalous activity indicative of data exfiltration

How to Mitigate CVE-2025-3345

Immediate Actions Required

• Restrict access to the /admin/combo.php endpoint using IP whitelisting or VPN requirements
• Implement a Web Application Firewall with SQL injection detection rules
• If possible, disable or remove the vulnerable functionality until a patch is available
• Review database permissions and apply principle of least privilege to limit potential damage from successful exploitation

Patch Information

No official patch has been released by the vendor at this time. Administrators should monitor the GitHub CVE Issue Discussion and VulDB entry for updates on remediation guidance.

Workarounds

• Implement input validation at the web server or reverse proxy level to reject requests containing SQL metacharacters in the del parameter
• Apply virtual patching through WAF rules to sanitize or block malicious input
• Restrict administrative interface access to trusted IP addresses only
• Consider taking the application offline if it processes sensitive data until proper remediation can be implemented

# Example: Restrict access to admin directory via Apache .htaccess
<Directory /var/www/html/admin>
    Order deny,allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Directory>
