CVE-2025-6902: Inventory Management System SQL Injection

CVE-2025-6902 Overview

A SQL injection vulnerability has been identified in Code-Projects Inventory Management System version 1.0. The vulnerability exists in the /php_action/editUser.php file, where the edituserName 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 within the 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 the vulnerable editUser.php endpoint.

Technical Details for CVE-2025-6902

Vulnerability Analysis

This SQL injection vulnerability (CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component) affects the user editing functionality within the Inventory Management System. The vulnerable endpoint /php_action/editUser.php accepts user input through the edituserName parameter without adequate input validation or parameterized query implementation. When user-supplied data is directly concatenated into SQL statements, attackers can craft malicious input that alters the intended query logic.

The vulnerability is remotely exploitable without authentication requirements, making it particularly concerning for internet-facing deployments. Successful exploitation could allow attackers to bypass authentication mechanisms, extract sensitive inventory and user data, or manipulate database records. The exploit has been publicly disclosed, increasing the risk of active exploitation in the wild.

Root Cause

The root cause of this vulnerability is insufficient input validation and the absence of prepared statements or parameterized queries in the editUser.php file. When the edituserName parameter is processed, special characters and SQL syntax are not properly escaped or neutralized, allowing attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

This vulnerability is exploitable remotely over the network. An attacker can send specially crafted HTTP requests to the /php_action/editUser.php endpoint with malicious SQL payload in the edituserName parameter. The attack requires no authentication and has low complexity, making it accessible to attackers with basic SQL injection knowledge.

The injection point allows attackers to manipulate SQL queries to:

• Extract database contents using UNION-based or blind SQL injection techniques
• Modify or delete existing database records
• Potentially escalate to command execution depending on database configuration and privileges

Detection Methods for CVE-2025-6902

Indicators of Compromise

• HTTP requests to /php_action/editUser.php containing SQL syntax characters such as single quotes ('), double dashes (--), semicolons (;), or UNION SELECT statements
• Database error messages appearing in application logs indicating malformed SQL queries
• Unexpected database queries containing concatenated strings or time-based delays
• Anomalous data access patterns or unauthorized data extraction from inventory tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the edituserName parameter
• Implement application-level logging to capture all requests to /php_action/editUser.php with parameter values for forensic analysis
• Configure database audit logging to track unusual query patterns or privilege escalation attempts
• Use intrusion detection systems (IDS) with signatures for common SQL injection payloads

Monitoring Recommendations

• Monitor web server access logs for repeated requests to editUser.php with suspicious parameter values
• Set up alerts for database errors indicating syntax issues in user-related queries
• Track failed authentication attempts following potential SQL injection activity
• Review database query logs for evidence of data exfiltration attempts

How to Mitigate CVE-2025-6902

Immediate Actions Required

• Restrict access to /php_action/editUser.php through network segmentation or access control lists until a patch is available
• Implement WAF rules to block requests containing SQL injection patterns in the edituserName parameter
• Consider taking the affected Inventory Management System offline if it handles sensitive data and cannot be adequately protected
• Review database logs for evidence of prior exploitation attempts

Patch Information

As of the last update on 2025-07-08, no official patch has been released by Code-Projects for this vulnerability. Organizations should monitor the Code Projects Security Resource for security updates and patch availability. Given the public disclosure of this exploit, prioritizing mitigation measures is essential.

Workarounds

• Implement prepared statements and parameterized queries in the editUser.php file if source code modification is possible
• Add server-side input validation to sanitize the edituserName parameter, rejecting inputs containing SQL metacharacters
• Deploy a reverse proxy or WAF with SQL injection detection capabilities in front of the application
• Restrict database user privileges to minimum required permissions to limit impact of successful injection

# Example WAF rule configuration (ModSecurity)
# Block SQL injection attempts on editUser.php endpoint
SecRule REQUEST_URI "@contains /php_action/editUser.php" \
    "id:100001,phase:2,deny,status:403,\
    chain"
SecRule ARGS:edituserName "@detectSQLi" \
    "t:none,t:urlDecodeUni,\
    msg:'SQL Injection attempt blocked on editUser.php'"
