CVE-2025-6118: Das Parking Management System SQL Injection

CVE-2025-6118 Overview

A SQL injection vulnerability has been identified in Das Parking Management System (停车场管理系统) version 6.2.0. This critical flaw exists in the /vehicle/search API endpoint where the vehicleTypeCode parameter is improperly handled, allowing attackers to inject malicious SQL statements. The vulnerability enables remote exploitation without authentication, potentially compromising the integrity and confidentiality of the parking management database.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to read, modify, or delete sensitive data within the parking management database, including vehicle records, user credentials, and financial transactions.

Affected Products

• Das Parking Management System (停车场管理系统) version 6.2.0
• API endpoint /vehicle/search component

Technical Details for CVE-2025-6118

Vulnerability Analysis

This vulnerability is classified as SQL Injection (CWE-89) and Injection (CWE-74). The flaw resides in the vehicle search functionality of the Das Parking Management System, specifically within the /vehicle/search API endpoint. When processing requests, the application fails to properly sanitize the vehicleTypeCode parameter before incorporating it into SQL queries. This lack of input validation allows attackers to inject arbitrary SQL code that the database server will execute.

The vulnerability is remotely exploitable and requires no authentication or user interaction. Successful exploitation can lead to unauthorized access to confidential vehicle and user data, modification of database records, and potential disruption of parking management operations.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries in the vehicle search functionality. The vehicleTypeCode parameter is directly concatenated into SQL statements without sanitization, escaping, or the use of prepared statements. This programming practice violates secure coding principles and enables injection attacks.

Attack Vector

The attack can be initiated remotely over the network by sending specially crafted HTTP requests to the /vehicle/search endpoint. An attacker constructs a malicious payload within the vehicleTypeCode parameter that breaks out of the intended SQL query structure and executes arbitrary database commands.

The vulnerability allows attackers to:

• Extract sensitive information from the database using UNION-based or blind SQL injection techniques
• Modify or delete vehicle records and user data
• Potentially escalate privileges within the application
• Compromise the underlying database server depending on database permissions

For detailed technical analysis and exploitation methodology, refer to the GitHub Document on Vehicle Search and VulDB advisory #312587.

Detection Methods for CVE-2025-6118

Indicators of Compromise

• Unusual or malformed HTTP requests to /vehicle/search endpoint containing SQL syntax characters such as single quotes, semicolons, or SQL keywords
• Database error messages or exceptions logged from the vehicle search functionality
• Unexpected database queries containing UNION SELECT, OR 1=1, or other SQL injection patterns
• Anomalous data access patterns in vehicle records or authentication tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the /vehicle/search endpoint
• Implement application-level logging for all API requests to the vehicle search functionality with payload inspection
• Configure database activity monitoring to alert on suspicious query patterns or unauthorized data access
• Enable intrusion detection system (IDS) signatures for SQL injection attack patterns

Monitoring Recommendations

• Monitor HTTP access logs for requests to /vehicle/search containing special characters or SQL keywords in the vehicleTypeCode parameter
• Set up alerts for database errors originating from the parking management application
• Review authentication logs for signs of privilege escalation following potential exploitation attempts

How to Mitigate CVE-2025-6118

Immediate Actions Required

• Restrict network access to the /vehicle/search API endpoint to trusted IP addresses only
• Implement input validation and sanitization for the vehicleTypeCode parameter at the application firewall level
• Review database permissions and apply least-privilege principles to the application's database user account
• Enable comprehensive logging for the affected endpoint to detect exploitation attempts

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations should monitor the vendor's official channels for security updates. Consider implementing the workarounds below until an official fix becomes available.

Additional information is available through VulDB CTI #312587 and the VulDB submission #591173.

Workarounds

• Deploy a Web Application Firewall (WAF) with SQL injection detection rules in front of the parking management system
• Implement network segmentation to isolate the parking management system from untrusted networks
• Apply input validation at the reverse proxy or API gateway level to filter malicious vehicleTypeCode values
• Consider disabling the vehicle search functionality if not business-critical until a patch is available
