CVE-2026-6153: Vehicle Showroom Management System SQLi

CVE-2026-6153 Overview

A SQL injection vulnerability has been identified in code-projects Vehicle Showroom Management System 1.0. The vulnerability affects the file /util/StaffDetailsFunction.php where improper handling of the STAFF_ID parameter allows attackers to inject malicious SQL commands. This vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to the underlying database and sensitive information.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete database contents, potentially compromising the entire Vehicle Showroom Management System and any sensitive data it manages.

Affected Products

• code-projects Vehicle Showroom Management System 1.0
• /util/StaffDetailsFunction.php component

Technical Details for CVE-2026-6153

Vulnerability Analysis

This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly referred to as injection. The affected application fails to properly sanitize or validate user-supplied input in the STAFF_ID parameter before incorporating it into SQL queries. This allows an attacker to manipulate the intended SQL query structure by injecting arbitrary SQL syntax.

The network-accessible nature of this vulnerability means attackers can exploit it remotely without requiring any authentication or user interaction. The exploit has been publicly disclosed, increasing the risk of opportunistic attacks against unpatched systems.

Root Cause

The root cause of this vulnerability lies in the improper handling of user input in the StaffDetailsFunction.php file. The STAFF_ID argument is directly incorporated into SQL queries without proper sanitization, parameterization, or use of prepared statements. This classic SQL injection pattern occurs when developers concatenate user input directly into SQL query strings rather than using parameterized queries or stored procedures.

Attack Vector

The vulnerability is exploitable via network access to the /util/StaffDetailsFunction.php endpoint. An attacker can craft malicious HTTP requests containing SQL injection payloads in the STAFF_ID parameter. Since no authentication is required and the attack can be performed remotely, the barrier to exploitation is low.

The attack flow typically involves:

1. Attacker identifies the vulnerable endpoint at /util/StaffDetailsFunction.php
2. Attacker crafts a malicious request with SQL injection payload in the STAFF_ID parameter
3. The application processes the unsanitized input and executes the injected SQL
4. Attacker extracts sensitive data or modifies database contents based on the injection technique used

Detection Methods for CVE-2026-6153

Indicators of Compromise

• Unusual SQL error messages in application logs related to /util/StaffDetailsFunction.php
• Abnormal requests to the StaffDetailsFunction.php endpoint containing SQL keywords such as UNION, SELECT, OR 1=1, or comment sequences like -- and /*
• Database query logs showing unexpected queries or syntax anomalies originating from the affected function
• Evidence of data exfiltration or unauthorized database access patterns

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the STAFF_ID parameter
• Monitor web server access logs for suspicious requests to /util/StaffDetailsFunction.php containing encoded or plaintext SQL injection attempts
• Enable database query logging and audit for anomalous query patterns
• Deploy intrusion detection systems with signatures for SQL injection attack patterns

Monitoring Recommendations

• Configure alerting for any HTTP requests to the vulnerable endpoint containing SQL metacharacters or injection keywords
• Establish baseline behavior for the StaffDetailsFunction.php endpoint and alert on deviations
• Monitor database connection activity from the web application for unusual query volumes or patterns
• Review application error logs regularly for SQL-related exceptions

How to Mitigate CVE-2026-6153

Immediate Actions Required

• Restrict access to the /util/StaffDetailsFunction.php endpoint until a patch is applied
• Implement input validation and sanitization for the STAFF_ID parameter as an interim measure
• Deploy WAF rules to block SQL injection attempts targeting the affected endpoint
• Review and audit database access logs for any signs of prior exploitation

Patch Information

No official vendor patch information is currently available. Organizations should monitor the Code Projects Security Resource for updates. Given that the exploit is publicly available, administrators should prioritize implementing workarounds and consider whether continued use of this application is appropriate for their security requirements.

For additional technical details, see the VulDB Submission #796315.

Workarounds

• Modify the StaffDetailsFunction.php file to use prepared statements or parameterized queries for all database interactions involving the STAFF_ID parameter
• Implement strict input validation to ensure STAFF_ID only accepts expected data types (typically numeric identifiers)
• Apply the principle of least privilege to the database user account used by the application
• Consider disabling or removing the affected functionality if it is not business-critical

# Example: Restrict access to vulnerable endpoint via Apache .htaccess
# Add to .htaccess in the web root or /util directory
<Files "StaffDetailsFunction.php">
    Order Deny,Allow
    Deny from all
    # Allow only from trusted management IPs if needed
    # Allow from 192.168.1.0/24
</Files>
