CVE-2025-7814: Food Ordering Review System SQLi Flaw

CVE-2025-7814 Overview

A critical SQL Injection vulnerability has been identified in the Carmelo Food Ordering Review System version 1.0. This vulnerability exists in the /pages/signup_function.php file, where the fname parameter is improperly handled, allowing attackers to inject malicious SQL queries. The flaw can be exploited remotely without authentication, potentially enabling unauthorized database access, data manipulation, or extraction of sensitive information. Other parameters in the affected file may also be vulnerable to similar injection attacks.

Critical Impact
Remote attackers can exploit this SQL Injection vulnerability to bypass authentication, extract sensitive user data, modify database records, or potentially gain further access to the underlying system through the publicly accessible signup functionality.

Technical Details for CVE-2025-7814

Vulnerability Analysis

This SQL Injection vulnerability stems from insufficient input validation in the signup functionality of the Food Ordering Review System. The fname parameter passed to /pages/signup_function.php is directly incorporated into SQL queries without proper sanitization or parameterization. This allows attackers to craft malicious input that modifies the intended SQL query logic.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where user-controlled input is not properly neutralized before being used in commands or queries. The attack is network-accessible and requires no authentication or user interaction, making it particularly dangerous for internet-facing installations.

Root Cause

The root cause of this vulnerability is the lack of proper input sanitization and the failure to use parameterized queries or prepared statements when handling the fname parameter in the signup function. User-supplied input is concatenated directly into SQL statements, allowing special SQL characters and commands to be interpreted by the database engine rather than treated as literal data.

Attack Vector

The attack vector is network-based, allowing remote exploitation through the web application's signup endpoint. An attacker can submit specially crafted values in the fname form field that contain SQL metacharacters and commands. When processed by /pages/signup_function.php, the malicious input alters the SQL query execution, potentially allowing:

Extraction of sensitive data from the database (usernames, passwords, personal information)
Bypassing authentication mechanisms
Modification or deletion of database records
In some configurations, execution of system commands through database features

The exploit has been publicly disclosed, increasing the risk of active exploitation. Additional parameters within the same file may also be vulnerable to similar injection techniques.

Detection Methods for CVE-2025-7814

Indicators of Compromise

Unusual or malformed HTTP POST requests to /pages/signup_function.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
Database error messages in application logs referencing syntax errors or unexpected query behavior
Anomalous database queries in database audit logs, particularly those with UNION SELECT, OR 1=1, or comment sequences
Evidence of data exfiltration or unexpected SELECT queries against sensitive tables

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the fname parameter and signup endpoints
Enable detailed logging on the web server and database to capture all queries executed against the Food Ordering Review System
Deploy intrusion detection systems with signatures for common SQL injection attack patterns
Monitor for unusual database access patterns or bulk data retrieval operations

Monitoring Recommendations

Configure real-time alerting for SQL syntax errors in application and database logs
Monitor network traffic for suspicious patterns targeting /pages/signup_function.php
Implement database activity monitoring to detect unauthorized queries or privilege escalation attempts
Review web server access logs regularly for reconnaissance activities targeting the signup functionality

How to Mitigate CVE-2025-7814

Immediate Actions Required

If possible, take the affected Food Ordering Review System offline or restrict network access until a patch is applied
Implement WAF rules to filter SQL injection attempts targeting the /pages/signup_function.php endpoint
Add input validation at the application layer to reject or sanitize special characters in user-supplied fields
Review and audit database permissions to minimize potential damage from successful exploitation

Patch Information

No official vendor patch has been identified in the available CVE data. Organizations should monitor the Code Projects Security Resources for updates. For detailed technical information about this vulnerability, refer to the GitHub Issue Discussion and VulDB #316918.

Given the absence of an official patch, organizations should consider implementing code-level fixes by modifying the vulnerable PHP file to use prepared statements with parameterized queries.

Workarounds

Implement a WAF with SQL injection detection rules in front of the application to filter malicious requests before they reach the vulnerable endpoint
Modify the source code to use PHP PDO or MySQLi prepared statements for all database queries involving user input
Apply strict input validation on the fname parameter, rejecting any input containing SQL metacharacters
Consider disabling the signup functionality temporarily if it is not critical to operations
Restrict database user privileges for the application to minimum required permissions
