CVE-2025-9842: Das Parking Management System Info Leak

CVE-2025-9842 Overview

A vulnerability has been identified in Das Parking Management System (停车场管理系统) version 6.2.0 that allows remote attackers to access sensitive information. This information disclosure vulnerability affects the /Operator/Search endpoint, where manipulation of requests results in unauthorized exposure of data. The vulnerability can be exploited remotely without authentication, and a public exploit is now available.

Critical Impact

Remote attackers can exploit this information disclosure vulnerability to access sensitive data from the parking management system without authentication, potentially exposing operator data, parking records, and system configuration details.

Technical Details for CVE-2025-9842

Vulnerability Analysis

This vulnerability is classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor). The flaw exists in the /Operator/Search endpoint of the Das Parking Management System, which fails to properly restrict access to sensitive information. When an attacker sends crafted requests to this endpoint, the application improperly discloses data that should be protected from unauthorized access.

The network-accessible nature of this vulnerability means it can be exploited remotely without any user interaction or special privileges required. This makes it particularly concerning for organizations running internet-exposed instances of this parking management software.

Root Cause

The root cause of this vulnerability stems from improper access control implementation in the /Operator/Search functionality. The application does not adequately validate authorization before returning search results, allowing unauthenticated or unauthorized users to retrieve sensitive information through the search interface. This represents a failure to implement proper data access restrictions on a potentially sensitive endpoint.

Attack Vector

The attack vector for CVE-2025-9842 is network-based, allowing remote exploitation. An attacker can target the /Operator/Search endpoint from any network location that can reach the vulnerable system. The attack requires no authentication, no user interaction, and has low complexity to execute.

The vulnerability can be exploited by sending specially crafted HTTP requests to the affected endpoint. Without proper access controls in place, the endpoint responds with sensitive information that should be restricted to authorized operators only.

For technical details on the exploitation methodology, see the GitHub Documentation Resource or the VulDB entry #322189.

Detection Methods for CVE-2025-9842

Indicators of Compromise

• Unusual or unexpected HTTP requests targeting the /Operator/Search endpoint
• High volume of search queries from unfamiliar IP addresses or geographic locations
• Access attempts to operator search functionality from non-administrative user accounts
• Abnormal data transfer volumes from the parking management system web server

Detection Strategies

• Implement web application firewall (WAF) rules to monitor and log access to the /Operator/Search endpoint
• Configure intrusion detection systems (IDS) to alert on enumeration patterns against the search functionality
• Review application logs for repeated or anomalous requests to the affected endpoint
• Monitor for unauthorized access attempts using SentinelOne Singularity XDR to correlate network and endpoint activity

Monitoring Recommendations

• Enable detailed access logging for all web application endpoints, particularly /Operator/Search
• Set up alerting for failed or suspicious authentication attempts to the parking management system
• Deploy network traffic analysis to identify reconnaissance activity targeting the application
• Conduct periodic security assessments of exposed parking management system instances

How to Mitigate CVE-2025-9842

Immediate Actions Required

• Restrict network access to the Das Parking Management System to trusted IP addresses only
• Implement authentication requirements for the /Operator/Search endpoint if not already present
• Deploy a web application firewall (WAF) to filter malicious requests targeting the vulnerable endpoint
• Review and audit access logs to determine if exploitation has already occurred

Patch Information

At the time of this publication, no official vendor patch has been released for CVE-2025-9842. Organizations should monitor the Das Parking Management System vendor communications for security updates. In the meantime, implement the recommended workarounds and defensive measures to reduce exposure.

For additional vulnerability details, refer to:

• VulDB CTI ID #322189
• VulDB Submission ID #641783

Workarounds

• Isolate the parking management system behind a VPN or firewall to prevent direct internet exposure
• Implement IP-based access controls to restrict access to the /Operator/Search endpoint to authorized administrative networks only
• Add application-level authentication and authorization checks before allowing access to search functionality
• Consider disabling the affected search functionality until a vendor patch is available

# Example: Restrict access to /Operator/Search using nginx
location /Operator/Search {
    # Allow only trusted IP ranges
    allow 10.0.0.0/8;
    allow 192.168.1.0/24;
    deny all;
    
    # Require authentication
    auth_basic "Restricted Access";
    auth_basic_user_file /etc/nginx/.htpasswd;
}
