CVE-2025-6960: Employee Management System SQLi Vulnerability

CVE-2025-6960 Overview

A critical SQL injection vulnerability has been identified in Campcodes Employee Management System version 1.0. The vulnerability exists in the /empproject.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially enabling unauthorized access to sensitive employee data, database manipulation, or complete system compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive employee records, modify database contents, or potentially gain further system access through the publicly accessible /empproject.php endpoint.

Affected Products

• Campcodes Employee Management System 1.0

Technical Details for CVE-2025-6960

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the /empproject.php endpoint in the Campcodes Employee Management System. The vulnerability allows unauthenticated remote attackers to manipulate database queries through the ID parameter, which is not properly sanitized before being incorporated into SQL statements.

The exploit has been publicly disclosed, increasing the risk of widespread exploitation. Attackers can leverage this vulnerability to bypass authentication mechanisms, extract confidential employee information including personal identifiable information (PII), modify or delete database records, and potentially escalate their access within the system.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of parameterized queries in the handling of the ID parameter within /empproject.php. User-supplied input is directly concatenated into SQL queries without proper sanitization or prepared statement usage, allowing attackers to inject arbitrary SQL commands that are executed by the database engine.

Attack Vector

The attack can be launched remotely over the network without requiring any authentication or user interaction. An attacker simply needs to craft a malicious HTTP request to the /empproject.php endpoint with a specially crafted ID parameter containing SQL injection payloads.

The vulnerability is exploited by manipulating the ID parameter in requests to /empproject.php. Attackers can inject SQL syntax such as ' OR '1'='1, UNION SELECT statements, or time-based blind injection payloads to extract data or manipulate the database. For detailed technical information about the exploitation technique, refer to the GitHub PoC Issue and VulDB entry #314497.

Detection Methods for CVE-2025-6960

Indicators of Compromise

• Unusual or malformed requests to /empproject.php containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences like -- and /*
• Database error messages exposed in HTTP responses indicating failed SQL query execution
• Unexpected database queries or operations logged in database audit logs
• Anomalous data access patterns to employee records from unfamiliar IP addresses

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the ID parameter
• Monitor web server access logs for requests to /empproject.php containing suspicious characters such as single quotes, semicolons, or SQL keywords
• Deploy database activity monitoring to detect unauthorized queries or bulk data extraction attempts
• Configure intrusion detection systems (IDS) with signatures for SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for all requests to the Employee Management System web application
• Set up real-time alerts for database errors or exceptions that may indicate injection attempts
• Monitor for unusual spikes in database read operations that could indicate data exfiltration
• Implement network traffic analysis to detect outbound data transfers following potential exploitation

How to Mitigate CVE-2025-6960

Immediate Actions Required

• Restrict network access to the Employee Management System to trusted IP ranges only
• Implement input validation and sanitization for all user-supplied parameters, particularly the ID parameter in /empproject.php
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules as an interim measure
• Review database access logs for any signs of prior exploitation

Patch Information

As of the last NVD update on 2025-07-07, no official vendor patch has been released for this vulnerability. Organizations using Campcodes Employee Management System 1.0 should contact the vendor for remediation guidance and monitor the CampCodes website for security updates. Additional technical details are available through VulDB #314497.

Workarounds

• Implement prepared statements or parameterized queries for all database interactions in /empproject.php
• Apply strict input validation to ensure the ID parameter contains only expected numeric values
• Deploy network segmentation to isolate the Employee Management System from public internet access
• Consider implementing additional authentication layers before allowing access to vulnerable endpoints

# Example: Apache .htaccess rules to restrict access to vulnerable endpoint
<Files "empproject.php">
    Order deny,allow
    Deny from all
    Allow from 192.168.1.0/24
    # Restrict to internal network only until patched
</Files>
