CVE-2025-6313: Sales And Inventory System SQL Injection

CVE-2025-6313 Overview

A critical SQL injection vulnerability has been identified in Campcodes Sales and Inventory System version 1.0. This security flaw affects the /pages/cat_add.php file, where improper handling of the Category parameter allows attackers to inject malicious SQL commands. The vulnerability can be exploited remotely without authentication, potentially enabling unauthorized access to the underlying database, data manipulation, and complete system compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive business data, modify inventory records, or potentially gain unauthorized access to the underlying database server.

Technical Details for CVE-2025-6313

Vulnerability Analysis

This SQL injection vulnerability exists in the category management functionality of Campcodes Sales and Inventory System. The cat_add.php file processes user-supplied input through the Category parameter without proper sanitization or parameterized queries. When an attacker submits specially crafted SQL syntax as the Category value, the malicious code is concatenated directly into database queries and executed by the backend database engine.

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 flaw can be exploited remotely over the network without requiring any authentication or user interaction, making it particularly dangerous for internet-facing deployments.

Root Cause

The root cause of this vulnerability is the absence of input validation and parameterized queries in the /pages/cat_add.php file. The application directly incorporates user-supplied data from the Category parameter into SQL statements without proper escaping or the use of prepared statements. This classic injection flaw allows attackers to break out of the intended query structure and execute arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely over the network by sending crafted HTTP requests to the vulnerable endpoint. An attacker would target the /pages/cat_add.php file and manipulate the Category parameter with SQL injection payloads. Depending on the database configuration and privileges, successful exploitation could lead to:

• Unauthorized data extraction from the database
• Modification or deletion of inventory and sales records
• Authentication bypass to gain administrative access
• Potential command execution if database features like xp_cmdshell (SQL Server) or INTO OUTFILE (MySQL) are available

The vulnerability requires no special privileges or user interaction to exploit, as the affected endpoint appears to be accessible without authentication. Technical details and proof-of-concept information have been disclosed publicly through the GitHub Issue #4 Report.

Detection Methods for CVE-2025-6313

Indicators of Compromise

• Unusual or malformed HTTP requests targeting /pages/cat_add.php with SQL syntax in the Category parameter
• Database error messages appearing in application logs or HTTP responses indicating SQL syntax errors
• Unexpected database queries containing SQL keywords like UNION, SELECT, DROP, or comment sequences (--, /*)
• Anomalous database access patterns or unauthorized data exports from the inventory system

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP requests
• Configure database activity monitoring to alert on suspicious query patterns or unauthorized access attempts
• Review web server access logs for requests to /pages/cat_add.php containing special characters or SQL keywords
• Deploy network intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for the Campcodes Sales and Inventory System application and associated database
• Monitor for multiple failed or unusual requests to the /pages/cat_add.php endpoint
• Set up alerts for database errors indicating potential injection attempts
• Implement real-time security monitoring using SentinelOne Singularity to detect exploitation attempts and anomalous process behavior

How to Mitigate CVE-2025-6313

Immediate Actions Required

• Restrict network access to the Campcodes Sales and Inventory System to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection filtering rules in front of the application
• Consider taking the application offline if it contains sensitive data and cannot be adequately protected
• Review database logs for signs of prior exploitation and assess potential data exposure

Patch Information

At the time of publication, no official patch has been released by Campcodes for this vulnerability. Organizations using the affected software should monitor the CampCodes official website and VulDB entry for updates. Until a patch is available, implementing the workarounds below is strongly recommended.

Workarounds

• Deploy a Web Application Firewall (WAF) to filter malicious SQL injection payloads before they reach the application
• Implement network segmentation to isolate the vulnerable application from critical systems
• Apply input validation at the application layer by modifying the cat_add.php file to use parameterized queries or prepared statements
• Restrict database user privileges to limit the impact of potential SQL injection attacks
• Consider migrating to a more actively maintained inventory management solution if the vendor does not provide timely security updates

For organizations using SentinelOne, the Singularity platform provides behavioral detection capabilities that can identify post-exploitation activities resulting from SQL injection attacks, including anomalous database access patterns and lateral movement attempts.
