CVE-2025-9843: Das Parking Management Information Leak

CVE-2025-9843 Overview

A significant information disclosure vulnerability has been identified in Das Parking Management System (停车场管理系统) version 6.2.0. The flaw exists in an unknown function of the file /Operator/FindAll, which when exploited allows unauthorized access to sensitive information. This vulnerability can be initiated remotely over a network without requiring authentication, making it particularly concerning for organizations using this parking management solution.

Critical Impact

Remote attackers can exploit this vulnerability to access sensitive operator information without authentication, potentially exposing user data, credentials, or system configuration details stored in the parking management system.

Affected Products

• Das Parking Management System 6.2.0
• das parking_management_system (CPE: cpe:2.3:a:das:parking_management_system:6.2.0:*:*:*:*:*:*:*)

Technical Details for CVE-2025-9843

Vulnerability Analysis

This vulnerability is classified as an Information Disclosure issue (CWE-200: Exposure of Sensitive Information to an Unauthorized Actor). The affected endpoint /Operator/FindAll appears to return operator data without proper authorization checks, allowing unauthenticated users to retrieve information that should be restricted to authorized administrators only.

The vulnerability requires no privileges or user interaction to exploit. An attacker simply needs network access to the affected system to query the vulnerable endpoint and retrieve sensitive information. While the confidentiality impact is limited (low), the ease of exploitation and the potential for data exposure make this a notable security concern for parking management deployments.

Root Cause

The root cause of this vulnerability is improper access control on the /Operator/FindAll endpoint. The application fails to validate whether the requesting user has the necessary permissions to access operator data before returning the information. This represents a broken access control issue where sensitive data is exposed due to missing or inadequate authorization checks on API endpoints.

Attack Vector

The attack can be conducted remotely over the network with low complexity. An attacker can send an unauthenticated HTTP request to the /Operator/FindAll endpoint to retrieve sensitive operator information. The exploit has been publicly disclosed and is available for use, increasing the risk of widespread exploitation.

The vulnerability manifests in the endpoint handling for /Operator/FindAll, where the application returns operator data without verifying authentication or authorization. For technical details on the exploitation methodology, refer to the GitHub Document on Parking and VulDB entry #322190.

Detection Methods for CVE-2025-9843

Indicators of Compromise

• Unusual or unauthorized HTTP requests to the /Operator/FindAll endpoint from external IP addresses
• High volume of requests to operator-related API endpoints from single sources
• Access logs showing queries to /Operator/FindAll without corresponding authentication events
• Network traffic patterns indicating data exfiltration from the parking management system

Detection Strategies

• Implement web application firewall (WAF) rules to monitor and alert on unauthenticated access attempts to /Operator/FindAll
• Configure intrusion detection systems (IDS) to flag suspicious request patterns targeting operator management endpoints
• Enable detailed access logging on the Das Parking Management System to track all API requests
• Deploy network monitoring to detect unusual outbound data transfers from the application server

Monitoring Recommendations

• Continuously monitor web server access logs for requests to /Operator/FindAll without valid session tokens
• Set up alerts for failed authentication attempts followed by direct API endpoint access
• Implement rate limiting on sensitive endpoints to slow down enumeration attempts
• Review application logs regularly for anomalous data access patterns

How to Mitigate CVE-2025-9843

Immediate Actions Required

• Restrict network access to the Das Parking Management System to trusted IP ranges only
• Implement authentication requirements for the /Operator/FindAll endpoint at the web server or reverse proxy level
• Review and audit access logs for any evidence of prior exploitation
• Consider taking the affected system offline until proper access controls can be implemented

Patch Information

No vendor patch information is currently available from Das for this vulnerability. Organizations should monitor the VulDB entry #322190 and vendor communications for updates on official fixes. In the meantime, implementing workarounds and compensating controls is strongly recommended.

Workarounds

• Deploy a web application firewall to block unauthenticated requests to /Operator/FindAll
• Implement network segmentation to isolate the parking management system from public networks
• Add IP-based access controls at the network or application level to restrict endpoint access
• Consider implementing a reverse proxy with authentication requirements for all API endpoints

# Example nginx configuration to restrict access to the vulnerable endpoint
location /Operator/FindAll {
    # Deny all unauthenticated access
    auth_basic "Restricted Access";
    auth_basic_user_file /etc/nginx/.htpasswd;
    
    # Alternative: Restrict by IP address
    # allow 192.168.1.0/24;
    # deny all;
    
    proxy_pass http://parking_backend;
