CVE-2025-6963: Campcodes Employee Management SQL Injection

CVE-2025-6963 Overview

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

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive employee information, modify database records, or potentially gain further access to the underlying system through database-level attacks.

Technical Details for CVE-2025-6963

Vulnerability Analysis

This SQL injection vulnerability in Campcodes Employee Management System stems from insufficient input validation in the /myprofile.php endpoint. The application fails to properly sanitize the ID parameter before incorporating it into SQL queries, creating a classic injection point that attackers can leverage remotely.

The vulnerability allows attackers to manipulate database queries without requiring any authentication or user interaction. By crafting malicious input for the ID parameter, an attacker can modify the logic of SQL statements executed against the backend database. This can result in unauthorized data extraction, modification of existing records, or deletion of critical information.

The exploit has been publicly disclosed, increasing the risk of active exploitation in the wild. Organizations using this employee management system should treat this vulnerability with urgency, as employee management systems typically contain sensitive personal information including names, addresses, contact details, payroll information, and other confidential data.

Root Cause

The root cause of CVE-2025-6963 is a CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) vulnerability. The application fails to implement proper input sanitization or parameterized queries when processing user-supplied input through the ID parameter in /myprofile.php. This allows special characters and SQL syntax to be interpreted as part of the query structure rather than as data values.

Attack Vector

The attack can be initiated remotely over the network. An attacker can craft HTTP requests to the /myprofile.php endpoint with a malicious ID parameter containing SQL injection payloads. Since no authentication is required and the attack can be automated, this vulnerability presents a significant risk to exposed instances of the Employee Management System.

The injection point in the ID parameter allows attackers to:

• Extract sensitive employee records from the database
• Modify or delete existing data
• Potentially escalate privileges within the application
• In some configurations, execute operating system commands through database functions

For technical details regarding the exploitation methodology, refer to the GitHub PoC Issue #41 and VulDB CVE Advisory #314500.

Detection Methods for CVE-2025-6963

Indicators of Compromise

• Unusual or malformed requests to /myprofile.php containing SQL syntax in the ID parameter
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database queries or access patterns in database audit logs
• Anomalous data extraction or bulk queries targeting employee tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the ID parameter
• Monitor HTTP access logs for requests to /myprofile.php with suspicious parameter values
• Enable database query logging and alert on queries with unusual syntax or union-based injections
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Set up real-time alerting for SQL error messages originating from the Employee Management System
• Establish baseline query patterns for the application and alert on deviations
• Monitor for unauthorized data access or bulk data exports from employee tables
• Review application and database logs regularly for signs of exploitation attempts

How to Mitigate CVE-2025-6963

Immediate Actions Required

• Restrict network access to the Campcodes Employee Management System to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Review database access logs for any signs of prior exploitation
• Consider taking the application offline until proper mitigations are in place

Patch Information

No official patch information is currently available from the vendor. Organizations should monitor CampCodes for security updates and patch releases. In the absence of an official patch, implementing the workarounds below is strongly recommended.

For additional technical details and updates, refer to the VulDB Advisory.

Workarounds

• Implement input validation to restrict the ID parameter to numeric values only
• Deploy a WAF rule to block requests containing SQL injection patterns in the ID parameter
• Use parameterized queries or prepared statements if modifying the application code is possible
• Apply the principle of least privilege to the database user account used by the application
• Implement network segmentation to limit database access from the web application tier only

# Example WAF rule for ModSecurity to block SQL injection in ID parameter
SecRule ARGS:ID "(?i)(\b(union|select|insert|update|delete|drop|exec|execute|xp_)\b|--|;|'|\")" \
    "id:100001,phase:2,deny,status:403,msg:'SQL Injection attempt detected in ID parameter'"
