CVE-2025-4746: Campcodes Sales And Inventory System SQLi

CVE-2025-4746 Overview

A critical SQL injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. This vulnerability exists in the file /pages/purchase_delete.php where improper handling of the pr_id parameter allows attackers to inject malicious SQL commands. The attack can be initiated remotely without authentication, potentially compromising the confidentiality, integrity, and availability of the underlying database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive data, modify database records, or potentially achieve further system compromise through database-level attacks.

Affected Products

• Campcodes Sales and Inventory System version 1.0

Technical Details for CVE-2025-4746

Vulnerability Analysis

This SQL injection vulnerability in Campcodes Sales and Inventory System stems from insufficient input validation in the purchase deletion functionality. The pr_id parameter in /pages/purchase_delete.php is directly incorporated into SQL queries without proper sanitization or parameterized query usage. This allows attackers to craft malicious input that alters the intended SQL query structure, enabling unauthorized database operations.

The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The network-accessible nature of this vulnerability means exploitation requires no local system access, and the low attack complexity indicates that minimal technical expertise is needed to exploit the flaw.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize user-supplied input before incorporating it into SQL queries. The pr_id parameter accepts user input directly without validation, escaping, or the use of prepared statements with parameterized queries. This is a classic example of trusting user input in a security-sensitive context, violating fundamental secure coding principles for database interactions.

Attack Vector

The attack vector is network-based, requiring no prior authentication or user interaction. An attacker can remotely send crafted HTTP requests to the /pages/purchase_delete.php endpoint with malicious SQL code embedded in the pr_id parameter. Depending on the database configuration and permissions, successful exploitation could allow the attacker to:

• Extract sensitive data from the database (customer information, inventory records, financial data)
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially execute operating system commands if database features like xp_cmdshell (SQL Server) or similar are enabled

The vulnerability is exploited by manipulating the pr_id parameter to include SQL metacharacters and commands. For example, an attacker might append SQL syntax such as ' OR '1'='1 or use UNION-based injection techniques to extract data from other tables. Technical details and proof-of-concept information can be found in the GitHub CVE Issue Discussion and VulDB entry #309046.

Detection Methods for CVE-2025-4746

Indicators of Compromise

• Unusual HTTP requests to /pages/purchase_delete.php containing SQL keywords or special characters in the pr_id parameter
• Database query errors or exceptions logged from the purchase deletion functionality
• Unexpected database queries or data access patterns originating from the web application
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Implement web application firewall (WAF) rules to detect SQL injection patterns in HTTP parameters
• Monitor application and database logs for suspicious query patterns or error messages indicating injection attempts
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection attack payloads
• Configure database activity monitoring to alert on unusual query patterns or bulk data access

Monitoring Recommendations

• Enable detailed logging on the web server for requests to /pages/purchase_delete.php
• Implement real-time alerting for database query errors and anomalous SQL execution patterns
• Monitor network traffic for suspicious payloads targeting the vulnerable endpoint
• Regularly audit database access logs for signs of unauthorized data retrieval

How to Mitigate CVE-2025-4746

Immediate Actions Required

• Restrict network access to the vulnerable endpoint /pages/purchase_delete.php until a patch can be applied
• Implement input validation and sanitization on the pr_id parameter as an interim measure
• Deploy a web application firewall (WAF) with SQL injection protection rules
• Review database permissions to ensure the application uses least-privilege access

Patch Information

As of the last update on June 3, 2025, no official vendor patch has been announced for this vulnerability. Organizations using Campcodes Sales and Inventory System should monitor the Campcodes website for security updates and apply patches immediately when available. Additional technical information is available through VulDB.

Workarounds

• Implement parameterized queries or prepared statements in the vulnerable PHP file to prevent SQL injection
• Add server-side input validation to ensure the pr_id parameter contains only expected numeric values
• Deploy a reverse proxy or WAF with SQL injection filtering capabilities in front of the application
• Consider temporarily disabling the purchase deletion functionality if it is not business-critical until proper remediation is completed

# Example WAF rule to block SQL injection attempts (ModSecurity)
SecRule ARGS:pr_id "@rx (\b(union|select|insert|update|delete|drop|alter|create|truncate)\b|['\";\-\-])" \
    "id:100001,phase:2,deny,status:403,msg:'SQL Injection Attempt Detected in pr_id parameter'"
