CVE-2025-4707: Campcodes Sales And Inventory System SQLi

CVE-2025-4707 Overview

A critical SQL Injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. The vulnerability exists in the /pages/transaction_add.php file, where improper handling of the prod_name parameter allows remote attackers to inject malicious SQL commands. This flaw enables unauthorized access to sensitive database information, data manipulation, and potential compromise of the entire application's backend database.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to extract sensitive data, modify database records, or potentially gain unauthorized access to the underlying system through database-level command execution.

Affected Products

• Campcodes Sales and Inventory System 1.0
• Applications using vulnerable /pages/transaction_add.php endpoint
• Deployments accepting user input via the prod_name parameter

Technical Details for CVE-2025-4707

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs in the transaction processing functionality of the Campcodes Sales and Inventory System. The vulnerable endpoint /pages/transaction_add.php fails to properly sanitize user-supplied input in the prod_name parameter before incorporating it into SQL queries. This allows attackers to break out of the intended query structure and execute arbitrary SQL commands against the backend database.

The vulnerability is network-accessible, requiring no authentication or user interaction to exploit. The attack complexity is low, making this an attractive target for automated exploitation tools and opportunistic attackers. Successful exploitation can compromise the confidentiality, integrity, and availability of data stored within the application's database.

Root Cause

The root cause of this vulnerability is inadequate input validation and the likely use of unsanitized user input in dynamic SQL query construction. The application appears to directly concatenate user-supplied data from the prod_name parameter into SQL statements without implementing proper parameterized queries, prepared statements, or input sanitization routines. This classic injection flaw (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) allows attackers to manipulate the intended query logic.

Attack Vector

The attack is initiated remotely over the network by sending crafted HTTP requests to the /pages/transaction_add.php endpoint. An attacker manipulates the prod_name parameter to inject SQL syntax that alters the behavior of the underlying database query. This could include UNION-based injection to extract data from other tables, boolean-based blind injection to enumerate database contents, or time-based injection techniques if other methods are filtered.

The vulnerability can be exploited by crafting malicious input in the prod_name parameter that breaks out of the expected query context. Attackers typically use SQL metacharacters such as single quotes, comment sequences, and UNION statements to manipulate query behavior.

Detection Methods for CVE-2025-4707

Indicators of Compromise

• Unusual or malformed requests to /pages/transaction_add.php containing SQL syntax in the prod_name parameter
• Database error messages appearing in application logs or responses indicating SQL syntax errors
• Unexpected database queries or access patterns detected in database audit logs
• Presence of SQL injection payloads such as ' OR 1=1--, UNION SELECT, or '; DROP TABLE in web server access logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the prod_name parameter
• Implement application-level logging for the /pages/transaction_add.php endpoint to capture all parameter values
• Configure database query logging to identify anomalous query structures or unexpected data access patterns
• Utilize intrusion detection systems (IDS) with SQL injection signature detection capabilities

Monitoring Recommendations

• Monitor web server access logs for requests to /pages/transaction_add.php with suspicious parameter values
• Enable database audit logging to track query execution and identify potential data exfiltration attempts
• Set up alerts for database errors that may indicate SQL injection attempts
• Review authentication and authorization logs for any unauthorized access following potential exploitation

How to Mitigate CVE-2025-4707

Immediate Actions Required

• Restrict network access to the vulnerable /pages/transaction_add.php endpoint until patching is complete
• Implement Web Application Firewall rules to block SQL injection attempts targeting the prod_name parameter
• Audit database access logs for evidence of prior exploitation attempts
• Consider temporarily disabling the transaction add functionality if business operations permit

Patch Information

No official vendor patch has been released for this vulnerability at the time of publication. Organizations using Campcodes Sales and Inventory System 1.0 should contact the vendor for remediation guidance. Monitor the Campcodes website for security updates. In the absence of an official patch, implementing the workarounds below is strongly recommended.

Workarounds

• Implement parameterized queries or prepared statements in the application code to prevent SQL injection
• Apply strict input validation to the prod_name parameter, rejecting any input containing SQL metacharacters
• Deploy a Web Application Firewall configured to detect and block SQL injection payloads
• Implement database user privilege restrictions to limit the impact of successful injection attacks
• Consider isolating the database server and restricting its network access to reduce lateral movement risk
