CVE-2025-3336: Online Restaurant Management System SQLi

CVE-2025-3336 Overview

A SQL injection vulnerability has been identified in codeprojects Online Restaurant Management System version 1.0. This vulnerability exists in the /admin/member_save.php file, where the last parameter is susceptible to SQL injection attacks due to improper input sanitization. The vulnerability can be exploited remotely without authentication, allowing attackers to manipulate database queries and potentially compromise the entire application and its underlying data.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database contents, or potentially gain unauthorized access to the underlying system through malicious SQL queries.

Technical Details for CVE-2025-3336

Vulnerability Analysis

This SQL injection vulnerability stems from inadequate input validation in the member management functionality of the Online Restaurant Management System. The affected endpoint /admin/member_save.php processes user-supplied input through the last parameter without proper sanitization or parameterized queries. When user input is directly concatenated into SQL statements, attackers can inject malicious SQL code that the database engine will execute.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating that the application fails to properly neutralize special characters before incorporating user input into SQL queries. The description notes that other parameters may also be affected, suggesting a systemic issue with input handling in this component.

Root Cause

The root cause is improper input validation and the use of dynamic SQL query construction without parameterized statements. The last parameter value is likely being directly interpolated into SQL queries without escaping special characters or using prepared statements. This allows attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The attack vector is network-based, requiring no authentication or user interaction. An attacker can craft malicious HTTP requests to the /admin/member_save.php endpoint with specially crafted values in the last parameter. By including SQL metacharacters and commands, the attacker can modify the query logic, extract data through UNION-based or error-based techniques, or execute stacked queries depending on the database configuration.

The vulnerability allows remote exploitation, meaning any attacker with network access to the application can attempt to inject SQL code. The admin path suggests this may be an authenticated admin function, but based on the reported network attack vector with no privileges required, the endpoint may be accessible without proper authentication controls.

Detection Methods for CVE-2025-3336

Indicators of Compromise

• Unusual HTTP requests to /admin/member_save.php containing SQL keywords such as UNION, SELECT, INSERT, DROP, or comment sequences like -- and /*
• Error messages in application logs indicating SQL syntax errors or unexpected database behavior
• Database logs showing anomalous query patterns or queries executing against unexpected tables
• Suspicious values in the last parameter containing special characters like single quotes, semicolons, or encoded SQL fragments

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns in requests to the affected endpoint
• Monitor HTTP traffic for requests containing common SQL injection payloads targeting the last parameter
• Configure database logging to capture and alert on query anomalies such as multiple statements, UNION operations, or access to system tables
• Deploy intrusion detection signatures for SQL injection attacks against PHP applications

Monitoring Recommendations

• Enable verbose logging on the web server to capture full request parameters for forensic analysis
• Set up real-time alerting for any requests to /admin/member_save.php containing potential injection patterns
• Monitor database query execution times and result set sizes for anomalies that could indicate data exfiltration attempts

How to Mitigate CVE-2025-3336

Immediate Actions Required

• Restrict access to the /admin/member_save.php endpoint using firewall rules or web server access controls until a patch is available
• Implement input validation on the last parameter to allow only expected character patterns
• Deploy a web application firewall with SQL injection protection in front of the application
• Review and audit all database accounts used by the application, ensuring they have minimal required privileges

Patch Information

No official vendor patch has been released at this time. The vulnerability has been publicly disclosed through GitHub CVE Issue Discussion and tracked in VulDB #303550. Organizations using this software should monitor these resources and the vendor for security updates.

Workarounds

• Implement prepared statements with parameterized queries in the PHP code to prevent SQL injection
• Add input validation to sanitize the last parameter and all other user inputs before use in database queries
• Use database stored procedures with parameterized inputs instead of dynamic SQL construction
• Implement a web application firewall rule specifically blocking suspicious input to the affected endpoint
