CVE-2025-6117: Das Parking Management System SQLi Flaw

CVE-2025-6117 Overview

A critical SQL injection vulnerability has been identified in Das Parking Management System (停车场管理系统) version 6.2.0. The vulnerability exists in the /Reservations/Search API endpoint, where improper sanitization of the Value argument allows attackers to inject malicious SQL commands. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to bypass authentication, extract sensitive data, modify database records, or potentially gain control of the underlying database server.

Affected Products

• Das Parking Management System 6.2.0
• Applications using the /Reservations/Search API component

Technical Details for CVE-2025-6117

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) represents a classic injection flaw (CWE-74) in the Das Parking Management System. The vulnerability resides in the API component handling reservation searches at the /Reservations/Search endpoint. When user-supplied input is passed through the Value parameter, it is incorporated directly into SQL queries without proper sanitization or parameterization.

The exploit has been publicly disclosed, increasing the risk of widespread exploitation. Attackers can leverage this vulnerability remotely without requiring authentication, making it particularly dangerous for internet-facing deployments.

Root Cause

The root cause is improper input validation and the failure to use parameterized queries or prepared statements when constructing SQL queries. The Value argument in the /Reservations/Search endpoint is directly concatenated into SQL statements, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The attack can be initiated remotely over the network. An attacker crafts a malicious HTTP request to the /Reservations/Search API endpoint with a specially crafted Value parameter containing SQL injection payloads. Since no authentication is required for exploitation, any network-accessible instance is at risk.

The SQL injection vulnerability in the Value parameter allows attackers to manipulate database queries by injecting SQL metacharacters and commands. Typical exploitation techniques include using single quotes to break string delimiters, UNION-based injection to extract data from other tables, or time-based blind injection to enumerate database contents. Technical details and proof-of-concept information can be found in the GitHub Documentation Repository.

Detection Methods for CVE-2025-6117

Indicators of Compromise

• Unusual or malformed requests to /Reservations/Search containing SQL syntax characters such as single quotes, double dashes, or semicolons
• Database error messages in application logs indicating SQL syntax errors
• Unexpected database query patterns or excessive database load from API endpoints
• Evidence of data exfiltration or unauthorized database modifications

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns in the Value parameter
• Monitor HTTP access logs for requests to /Reservations/Search containing SQL injection signatures
• Implement database activity monitoring to detect anomalous queries or unauthorized data access
• Use intrusion detection systems (IDS) with SQL injection detection signatures

Monitoring Recommendations

• Enable detailed logging on the Das Parking Management System API endpoints
• Configure alerting for database errors or exceptions related to malformed SQL queries
• Monitor network traffic for suspicious patterns targeting the /Reservations/Search endpoint
• Review database audit logs regularly for unauthorized access attempts

How to Mitigate CVE-2025-6117

Immediate Actions Required

• Restrict network access to the Das Parking Management System to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Disable or restrict access to the /Reservations/Search endpoint until a patch is available
• Review database user permissions and apply principle of least privilege

Patch Information

No official vendor patch information is currently available. Organizations should monitor the vendor's official channels for security updates. For additional vulnerability intelligence, refer to VulDB #312586 and the VulDB Submission #591161.

Workarounds

• Implement input validation on the Value parameter at the application or WAF level
• Use a reverse proxy to filter and sanitize incoming requests to vulnerable endpoints
• Apply network segmentation to isolate the parking management system from untrusted networks
• Consider disabling the affected API endpoint if not critical to operations
