CVE-2026-37341: Vehicle Parking Management System SQLi

CVE-2026-37341 Overview

SourceCodester Vehicle Parking Area Management System v1.0 contains a SQL Injection vulnerability in the file /parking/manage_category.php. This vulnerability allows attackers to inject malicious SQL queries through user-controlled input, potentially leading to unauthorized access to sensitive database information, data manipulation, or complete database compromise.

Critical Impact

SQL Injection vulnerability enables attackers to bypass authentication, extract sensitive data, modify or delete database records, and potentially achieve remote code execution on the underlying database server.

Technical Details for CVE-2026-37341

Vulnerability Analysis

This SQL Injection vulnerability exists in the /parking/manage_category.php file of the Vehicle Parking Area Management System. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries, allowing attackers to manipulate the query structure and execute arbitrary SQL commands against the backend database.

SQL Injection vulnerabilities in web applications typically arise when dynamic SQL queries are constructed using string concatenation with unsanitized user input. In this case, the manage_category.php endpoint appears to accept parameters that are directly embedded into database queries without proper validation or parameterization.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries (prepared statements) in the manage_category.php file. The application directly concatenates user-controlled input into SQL query strings, creating an injection point that attackers can exploit to alter the intended query logic.

Attack Vector

An attacker can exploit this vulnerability by submitting specially crafted input containing SQL syntax to the vulnerable endpoint. The malicious input is processed by the application and executed as part of the database query, allowing the attacker to:

• Extract sensitive information from the database through UNION-based or error-based injection techniques
• Bypass authentication mechanisms by manipulating WHERE clauses
• Modify or delete existing database records
• Potentially execute administrative operations on the database server
• In some configurations, read or write files on the underlying server

Detection Methods for CVE-2026-37341

Indicators of Compromise

• Unusual or malformed HTTP requests to /parking/manage_category.php containing SQL keywords such as UNION, SELECT, INSERT, UPDATE, DELETE, or comment sequences (--, /**/)
• Web server logs showing URL-encoded SQL injection attempts targeting the category management endpoint
• Database error messages exposed in application responses indicating query manipulation
• Unexpected database query execution patterns or elevated query volumes from the web application

Detection Strategies

• Deploy web application firewalls (WAF) with SQL injection detection rules to monitor and block malicious requests to the affected endpoint
• Implement application-level logging to capture all input parameters submitted to manage_category.php
• Configure database audit logging to track anomalous query patterns and unauthorized data access attempts
• Use intrusion detection systems (IDS) with signatures for common SQL injection patterns

Monitoring Recommendations

• Monitor web server access logs for suspicious requests containing SQL metacharacters targeting /parking/manage_category.php
• Set up alerts for database errors or exceptions that may indicate injection attempts
• Review database query logs for unusual SELECT statements, especially those using UNION operators or accessing sensitive tables
• Implement real-time monitoring of database user activity to detect privilege escalation attempts

How to Mitigate CVE-2026-37341

Immediate Actions Required

• Restrict network access to the Vehicle Parking Area Management System to trusted IP addresses only
• Implement web application firewall rules to filter SQL injection attempts targeting the vulnerable endpoint
• Consider disabling or restricting access to the manage_category.php functionality until a patch is available
• Review and audit database permissions to ensure the application uses least-privilege database accounts

Patch Information

No official vendor patch has been identified at this time. Organizations using SourceCodester Vehicle Parking Area Management System v1.0 should monitor the vendor's website and the GitHub SQL Injection Report for updates and remediation guidance.

Workarounds

• Implement input validation on all user-supplied parameters to the manage_category.php endpoint, rejecting requests containing SQL metacharacters
• Deploy a reverse proxy or WAF configured with strict SQL injection filtering rules
• Modify the application code to use parameterized queries (prepared statements) instead of string concatenation for database operations
• Apply network segmentation to isolate the vulnerable application from critical systems
