CVE-2025-6123 Overview
A critical SQL injection vulnerability has been identified in code-projects Restaurant Order System version 1.0. This vulnerability exists in the /payment.php file, where improper handling of the tabidNoti parameter allows attackers to inject malicious SQL queries. The attack can be executed remotely without authentication, and proof-of-concept exploit code has been publicly disclosed.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database records, or potentially compromise the underlying database server through the publicly accessible payment processing endpoint.

Technical Details for CVE-2025-6123
Vulnerability Analysis
This SQL injection vulnerability resides in the payment processing functionality of the Restaurant Order System application. The tabidNoti parameter in /payment.php is passed directly to database queries without proper sanitization or parameterized query handling. This allows an attacker to manipulate the SQL query structure by injecting malicious SQL code through HTTP requests.
The vulnerability is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). Since the vulnerability is network-accessible and requires no authentication or user interaction to exploit, it presents a significant risk to deployments of this application that are exposed to untrusted networks.
Root Cause
The root cause of this vulnerability is the failure to properly sanitize user-supplied input in the tabidNoti parameter before incorporating it into SQL queries. The application directly concatenates user input into SQL statements rather than using prepared statements or parameterized queries, which is a fundamental secure coding violation for database interactions.
Attack Vector
The attack can be initiated remotely over the network by sending crafted HTTP requests to the /payment.php endpoint. An attacker can manipulate the tabidNoti parameter to inject SQL syntax that alters the intended query logic. This could enable data extraction through UNION-based injection, authentication bypass, data modification, or in some database configurations, command execution on the underlying server.
The vulnerability does not require authentication, making any publicly accessible deployment immediately vulnerable to exploitation. The exploit has been disclosed publicly, increasing the likelihood of active exploitation attempts.
Detection Methods for CVE-2025-6123
Indicators of Compromise
- Unusual SQL error messages in web server logs referencing /payment.php or the tabidNoti parameter
- HTTP requests to /payment.php containing SQL keywords such as UNION, SELECT, DROP, or comment sequences (--, /*)
- Database query logs showing malformed or unexpected queries originating from the payment module
- Unexpected database access patterns or data exfiltration activity
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the tabidNoti parameter
- Implement database activity monitoring to alert on anomalous query patterns or unauthorized data access
- Review web server access logs for requests to /payment.php containing URL-encoded SQL metacharacters
- Enable verbose database logging to capture and analyze query execution patterns
Monitoring Recommendations
- Configure real-time alerting for SQL injection attack signatures targeting payment-related endpoints
- Monitor for unusual outbound data transfers from the database server
- Implement application-level logging to track parameter values submitted to /payment.php
- Establish baseline database query patterns to detect deviations indicative of injection attacks
How to Mitigate CVE-2025-6123
Immediate Actions Required
- Immediately restrict access to /payment.php from untrusted networks using firewall rules or access control lists
- Consider taking the Restaurant Order System offline until a patch is applied or the vulnerable code is remediated
- Implement input validation on the tabidNoti parameter to reject non-numeric or malformed input
- Deploy a WAF with SQL injection protection rules as an interim mitigation measure
Patch Information
No official vendor patch has been released at this time. Organizations using this software should monitor the Code Projects Resource for security updates. Additional technical details about this vulnerability are available at the VulDB #312592 advisory and the GitHub PoC Issue Tracker.
Workarounds
- Modify the /payment.php source code to use prepared statements with parameterized queries for all database interactions
- Implement strict input validation to ensure tabidNoti contains only expected numeric values
- Deploy application-level whitelisting to restrict acceptable input patterns for the vulnerable parameter
- Place the application behind a reverse proxy with SQL injection detection capabilities
# Example: Apache mod_rewrite rule to block suspicious requests to payment.php
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|update|delete|drop|--|;|'|") [NC]
RewriteRule ^payment\.php$ - [F,L]
