CVE-2026-6152: Vehicle Showroom Management System SQLi

CVE-2026-6152 Overview

A SQL injection vulnerability has been identified in code-projects Vehicle Showroom Management System 1.0. This vulnerability exists in the /util/StaffAddingFunction.php file, where improper handling of the STAFF_ID argument allows attackers to inject malicious SQL statements. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, or further system compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete database contents, potentially compromising customer information, staff records, and business-critical data in vehicle showroom systems.

Affected Products

• code-projects Vehicle Showroom Management System 1.0
• Systems running /util/StaffAddingFunction.php with vulnerable STAFF_ID parameter handling

Technical Details for CVE-2026-6152

Vulnerability Analysis

This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as Injection. The flaw resides in the StaffAddingFunction.php file within the Vehicle Showroom Management System, where user-supplied input through the STAFF_ID parameter is not properly sanitized before being incorporated into SQL queries. This allows attackers to craft malicious input that alters the intended SQL logic, enabling unauthorized database operations.

The exploit has been publicly disclosed, increasing the risk of active exploitation. Organizations running this software should treat remediation as a priority given the network-accessible nature of the attack vector and the lack of authentication requirements.

Root Cause

The root cause of this vulnerability is insufficient input validation and lack of parameterized queries in the StaffAddingFunction.php file. When processing the STAFF_ID argument, the application directly concatenates user input into SQL statements without proper sanitization or use of prepared statements. This failure to neutralize special characters allows SQL syntax to be injected and executed by the database engine.

Attack Vector

The attack can be initiated remotely over the network. An unauthenticated attacker can submit specially crafted HTTP requests to the /util/StaffAddingFunction.php endpoint, manipulating the STAFF_ID parameter to include SQL injection payloads. Successful exploitation could allow the attacker to:

• Extract sensitive data from the database including customer and staff records
• Modify or delete database entries
• Potentially escalate privileges within the application
• In some configurations, execute operating system commands through database functions

The vulnerability requires no user interaction and can be exploited with low attack complexity, making it an attractive target for automated scanning and exploitation tools.

Detection Methods for CVE-2026-6152

Indicators of Compromise

• Unusual or malformed requests to /util/StaffAddingFunction.php containing SQL syntax in parameters
• Database error messages appearing in application logs referencing the STAFF_ID field
• Unexpected database queries or data modifications in audit logs
• Anomalous outbound connections from the database server

Detection Strategies

• Implement web application firewall (WAF) rules to detect SQL injection patterns in requests to StaffAddingFunction.php
• Monitor application and database logs for SQL syntax errors or unusual query patterns
• Deploy intrusion detection signatures for common SQL injection payloads targeting the STAFF_ID parameter

Monitoring Recommendations

• Enable detailed logging for the /util/ directory and all PHP file access
• Configure database query logging to capture and alert on anomalous SQL statements
• Implement real-time alerting for multiple failed database queries from the same source

How to Mitigate CVE-2026-6152

Immediate Actions Required

• Restrict network access to the /util/StaffAddingFunction.php endpoint using firewall rules or access controls
• Implement input validation to allow only expected characters (alphanumeric) in the STAFF_ID parameter
• Deploy a web application firewall with SQL injection detection rules
• Consider temporarily disabling the affected functionality if not business-critical

Patch Information

No official vendor patch has been identified at this time. Organizations should monitor the Code Projects website for security updates. Additional technical details about this vulnerability are available through the GitHub CVE Issue and VulDB entry.

Workarounds

• Implement prepared statements with parameterized queries in the affected PHP file to prevent SQL injection
• Add server-side input validation to sanitize the STAFF_ID parameter before database operations
• Deploy application-layer filtering to block requests containing SQL metacharacters
• Restrict database user privileges to limit the impact of successful exploitation

# Example: Apache configuration to restrict access to vulnerable endpoint
<Location "/util/StaffAddingFunction.php">
    Order deny,allow
    Deny from all
    Allow from 192.168.1.0/24
</Location>
