CVE-2025-6958: Employee Management System SQLi Vulnerability

CVE-2025-6958 Overview

A critical SQL injection vulnerability has been identified in Campcodes Employee Management System version 1.0. This security flaw exists in the /edit.php file where improper handling of the ID parameter allows remote attackers to inject malicious SQL commands. The vulnerability has been publicly disclosed and proof-of-concept exploit code is available, increasing the risk of active exploitation.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive employee data, modify database records, or potentially gain unauthorized access to the underlying database system without authentication.

Technical Details for CVE-2025-6958

Vulnerability Analysis

This SQL injection vulnerability affects the /edit.php endpoint in the Campcodes Employee Management System. The application fails to properly sanitize user-supplied input passed through the ID parameter before incorporating it into SQL queries. This allows attackers to manipulate the query structure and execute arbitrary SQL commands against the backend database.

The vulnerability is remotely exploitable without requiring any authentication or user interaction, making it particularly dangerous for internet-facing deployments. Successful exploitation could result in unauthorized data access, data modification, or complete database compromise depending on the database configuration and permissions.

Root Cause

The root cause of this vulnerability is improper input validation and lack of parameterized queries (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component). The application directly concatenates user-controlled input from the ID parameter into SQL statements without adequate sanitization or the use of prepared statements, creating a classic SQL injection attack surface.

Attack Vector

The attack can be initiated remotely over the network. An attacker sends specially crafted HTTP requests to the /edit.php endpoint with malicious SQL syntax embedded in the ID parameter. The vulnerable application processes this input and executes the injected SQL commands against the database.

The exploitation mechanism involves injecting SQL syntax through the ID parameter in requests to /edit.php. Attackers can leverage techniques such as UNION-based injection, boolean-based blind injection, or time-based blind injection to extract data or manipulate database contents. Technical details and proof-of-concept information are available through the GitHub PoC Issue #36 and VulDB #314495.

Detection Methods for CVE-2025-6958

Indicators of Compromise

• Unusual or malformed requests to /edit.php containing SQL syntax characters such as single quotes, semicolons, or SQL keywords in the ID parameter
• Database error messages appearing in application logs or HTTP responses indicating SQL syntax errors
• Unexpected database queries or access patterns in database audit logs
• Evidence of data exfiltration or unauthorized data modifications in employee records

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the ID parameter
• Monitor application logs for requests to /edit.php with suspicious ID parameter values containing SQL metacharacters
• Enable database query logging and alert on anomalous query patterns or error conditions
• Deploy intrusion detection systems with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Configure real-time alerting for any SQL errors generated by the Employee Management System application
• Monitor network traffic for unusual data volumes being transmitted from the database server
• Implement database activity monitoring to track all queries executed against employee data tables
• Review access logs regularly for patterns indicative of automated SQL injection scanning tools

How to Mitigate CVE-2025-6958

Immediate Actions Required

• Restrict network access to the Employee Management System to trusted networks or IP addresses only
• Implement a web application firewall with SQL injection protection rules in front of the application
• Disable or remove the /edit.php functionality if not critical to operations until a patch is available
• Review database permissions and apply the principle of least privilege to the application's database account

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations should monitor the CampCodes website for security updates. Additional vulnerability tracking information is available through VulDB CTI #314495 and VulDB Submission #605897.

Workarounds

• Deploy input validation at the application or WAF layer to block requests containing SQL injection patterns in the ID parameter
• Place the application behind a reverse proxy that sanitizes input parameters before forwarding requests
• If source code access is available, implement parameterized queries or prepared statements for all database interactions
• Consider migrating to an alternative employee management solution until the vendor addresses this vulnerability
