CVE-2025-4719: Campcodes Sales Inventory System SQLi

CVE-2025-4719 Overview

A critical SQL Injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. The vulnerability exists within the /pages/cash_transaction.php file, where the cid parameter is not properly sanitized before being used in SQL queries. This allows remote attackers to inject malicious SQL commands, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, bypass authentication, modify database contents, or potentially gain further access to the underlying system through database manipulation.

Affected Products

• Campcodes Sales and Inventory System version 1.0

Technical Details for CVE-2025-4719

Vulnerability Analysis

This vulnerability is a classic SQL Injection flaw (CWE-89) resulting from improper neutralization of special elements used in SQL commands. The vulnerable endpoint /pages/cash_transaction.php accepts a cid parameter that is directly incorporated into SQL queries without adequate input validation or parameterization. This allows attackers to inject arbitrary SQL syntax that gets executed by the backend database.

The exploit has been publicly disclosed, increasing the risk of active exploitation. Organizations using this inventory management system should treat this as a high-priority remediation item, as the vulnerability can be exploited remotely without authentication.

Root Cause

The root cause is insufficient input validation and the lack of prepared statements or parameterized queries when handling the cid parameter. User-supplied input is directly concatenated into SQL query strings, enabling injection attacks. This represents a violation of secure coding practices where all user input should be treated as untrusted and properly sanitized before database operations.

Attack Vector

The attack can be launched remotely over the network without requiring any authentication or user interaction. An attacker can craft malicious HTTP requests containing SQL injection payloads in the cid parameter to the /pages/cash_transaction.php endpoint. The injected SQL commands execute with the privileges of the database user configured for the application, potentially allowing:

• Extraction of sensitive business data including sales records and inventory information
• Modification or deletion of database records
• Enumeration of database schema and table structures
• Potential escalation to operating system command execution depending on database configuration

The vulnerability allows manipulation of database queries by injecting malicious SQL syntax through the cid parameter. For technical details and proof-of-concept information, refer to the GitHub CVE Issue Discussion and VulDB CVE Report.

Detection Methods for CVE-2025-4719

Indicators of Compromise

• Unusual or malformed requests to /pages/cash_transaction.php containing SQL syntax characters in the cid parameter
• Database logs showing unexpected queries, error messages, or unauthorized data access patterns
• Web server access logs containing URL-encoded SQL injection payloads such as UNION SELECT, OR 1=1, or comment sequences
• Unexpected database performance degradation or query timeouts indicating data exfiltration attempts

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the cid parameter
• Configure database activity monitoring to alert on anomalous query patterns or unauthorized access attempts
• Enable detailed logging on the web application to capture all requests to cash_transaction.php with full parameter values
• Deploy intrusion detection systems with signatures for SQL injection attack patterns

Monitoring Recommendations

• Monitor web server logs for requests to /pages/cash_transaction.php containing suspicious characters or SQL keywords
• Set up alerts for database errors or exceptions that may indicate failed injection attempts
• Track application authentication logs for signs of bypass attempts
• Review database audit logs for bulk data access or schema enumeration queries

How to Mitigate CVE-2025-4719

Immediate Actions Required

• Restrict network access to the affected application until patches can be applied
• Implement input validation and WAF rules to filter malicious requests to the cid parameter
• Consider disabling or restricting access to the /pages/cash_transaction.php endpoint if not immediately required
• Review database permissions to ensure the application uses least-privilege database accounts

Patch Information

No official patch information is currently available from the vendor. Organizations should monitor Campcodes for security updates and patches. In the absence of vendor patches, consider implementing virtual patching through WAF rules or migrating to alternative inventory management solutions with better security practices.

Workarounds

• Deploy a Web Application Firewall configured to block SQL injection attempts targeting the vulnerable parameter
• Implement server-side input validation to reject cid values containing SQL metacharacters
• Restrict access to the application through network segmentation or IP whitelisting
• If source code access is available, modify the application to use parameterized queries or prepared statements for all database operations
