CVE-2026-7114: Employee Management System SQLi Vulnerability

CVE-2026-7114 Overview

A SQL injection vulnerability has been identified in code-projects Employee Management System 1.0. The vulnerability exists in the edit.php file within the 370project directory, where improper handling of the ID argument allows attackers to inject malicious SQL statements. This vulnerability can be exploited remotely by authenticated attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Attackers can exploit this SQL injection flaw to bypass authentication, extract sensitive employee data, or modify database records through malicious SQL queries injected via the ID parameter.

Affected Products

• code-projects Employee Management System 1.0
• File: 370project/edit.php

Technical Details for CVE-2026-7114

Vulnerability Analysis

This SQL injection vulnerability stems from inadequate input validation in the Employee Management System's edit functionality. The edit.php file accepts user-controlled input through the ID parameter without proper sanitization or parameterized queries. When an authenticated user submits a request to edit employee records, the application directly incorporates the ID value into SQL queries, creating an injection point that attackers can exploit.

The vulnerability allows authenticated attackers to execute arbitrary SQL commands against the underlying database. This could result in unauthorized access to sensitive employee information, modification of existing records, or potential privilege escalation within the application. The exploit has been publicly disclosed, increasing the risk of active exploitation.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries (prepared statements) when processing the ID argument in 370project/edit.php. The application directly concatenates user-supplied input into SQL queries without sanitization, escaping, or use of prepared statements, which is a fundamental violation of secure coding practices for database interactions.

Attack Vector

The attack is network-based and requires the attacker to have low-level privileges (authenticated access) to the application. An attacker can craft malicious HTTP requests containing SQL injection payloads within the ID parameter. When the vulnerable edit.php script processes these requests, the injected SQL code is executed by the database server.

The vulnerability affects confidentiality, integrity, and availability of the data stored in the Employee Management System database. Attackers could use techniques such as UNION-based injection, error-based injection, or blind SQL injection to extract database contents, modify records, or potentially escalate their access within the system.

Detection Methods for CVE-2026-7114

Indicators of Compromise

• Unusual SQL error messages appearing in application logs or web responses containing database syntax errors
• HTTP requests to 370project/edit.php containing SQL keywords or special characters (e.g., ', --, UNION, SELECT) in the ID parameter
• Unexpected database query patterns or abnormal query execution times in database logs
• Unauthorized data access or modifications to employee records without corresponding legitimate user actions

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the ID parameter
• Monitor HTTP access logs for requests to edit.php containing suspicious payloads or URL-encoded SQL syntax
• Deploy database activity monitoring to detect anomalous queries originating from the Employee Management System
• Use application security testing tools to regularly scan for SQL injection vulnerabilities in the affected endpoint

Monitoring Recommendations

• Enable detailed logging for the 370project/edit.php endpoint and regularly review logs for injection attempts
• Configure database audit logging to track all queries executed against employee data tables
• Set up alerts for multiple failed or malformed database queries within short time windows
• Monitor for data exfiltration indicators such as large result sets or unusual database export operations

How to Mitigate CVE-2026-7114

Immediate Actions Required

• Restrict access to 370project/edit.php to only trusted administrators until a patch is available
• Implement input validation to accept only numeric values for the ID parameter
• Deploy a Web Application Firewall (WAF) with SQL injection detection rules as a compensating control
• Review application logs and database audit trails for evidence of prior exploitation attempts

Patch Information

As of the last NVD update on 2026-04-29, no official vendor patch has been released for this vulnerability. Organizations should monitor the Code Projects website for security updates. In the absence of an official patch, organizations must rely on workarounds and compensating controls to mitigate the risk.

Additional vulnerability details are available at the VulDB Vulnerability #359714 entry.

Workarounds

• Implement prepared statements (parameterized queries) by modifying the edit.php source code to use PDO or MySQLi with bound parameters
• Add strict input validation to ensure the ID parameter contains only integer values before processing
• Deploy network-level access controls to limit who can reach the vulnerable endpoint
• Consider temporarily disabling the employee edit functionality if it is not business-critical until proper fixes can be implemented

# Example: Input validation configuration for Apache mod_security
SecRule ARGS:ID "!@rx ^[0-9]+$" \
    "id:100001,phase:2,deny,status:403,msg:'Invalid ID parameter - potential SQL injection'"
