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

CVE-2025-9842 Overview

CVE-2025-9842 is an information disclosure vulnerability in Das Parking Management System (停车场管理系统) version 6.2.0. The flaw resides in an unspecified function within the /Operator/Search endpoint. Attackers can manipulate this endpoint remotely to expose sensitive data without authentication or user interaction. The vendor product is developed by Das, and the issue is tracked under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor. Public disclosure of the exploit increases the risk of opportunistic abuse against exposed instances.

Critical Impact

Remote, unauthenticated attackers can retrieve sensitive information from the /Operator/Search endpoint of Das Parking Management System 6.2.0, with exploit details now publicly available.

Technical Details for CVE-2025-9842

Vulnerability Analysis

The vulnerability affects the /Operator/Search endpoint of Das Parking Management System 6.2.0. An attacker can manipulate request parameters to this endpoint and cause the application to return information that should not be exposed to unauthenticated users. Because the attack vector is network-based and requires no privileges or user interaction, an attacker only needs reachability to the web interface to attempt exploitation.

Information disclosure flaws of this class [CWE-200] commonly leak operator identifiers, internal configuration data, parking records, or other application state. Such data supports follow-on attacks including credential targeting, business logic abuse, and reconnaissance for additional vulnerabilities in the same application.

The exploit has been disclosed publicly via VulDB entry #322189 and a supporting documentation guide on GitHub. Public availability lowers the barrier to weaponization against unpatched deployments.

Root Cause

The root cause is improper restriction of sensitive data returned by the /Operator/Search function. The endpoint does not adequately enforce authorization or output filtering on data it returns. Manipulation of input parameters allows an external requester to obtain content intended for privileged operators.

Attack Vector

Exploitation occurs over the network against the exposed web interface. The attacker sends a crafted HTTP request to /Operator/Search without prior authentication. The response includes information that the application should not disclose. No client-side interaction, social engineering, or local access is required.

No verified exploitation code has been published in a structured proof-of-concept format. Refer to the VulDB CTI entry and the linked GitHub documentation for additional technical details.

Detection Methods for CVE-2025-9842

Indicators of Compromise

• Unauthenticated HTTP GET or POST requests to the /Operator/Search path from external IP addresses.
• Anomalous response sizes from /Operator/Search indicating bulk data extraction.
• Repeated parameter enumeration requests against the /Operator/Search endpoint within a short interval.

Detection Strategies

• Inspect web server and application access logs for requests to /Operator/Search lacking valid session cookies or authentication tokens.
• Deploy web application firewall (WAF) rules to flag requests to operator-scoped endpoints originating from unauthenticated sessions.
• Correlate HTTP request patterns with response payload size to identify scraping or enumeration behavior.

Monitoring Recommendations

• Forward web access logs to a centralized SIEM and build alerts for high-frequency access to administrative paths.
• Monitor outbound traffic from the parking management server for unexpected data egress.
• Track new external scanners or user-agents probing the application after the September 2025 disclosure date.

How to Mitigate CVE-2025-9842

Immediate Actions Required

• Restrict network access to the Das Parking Management System web interface using firewall rules or a VPN, limiting it to trusted operator networks.
• Place the application behind a reverse proxy or WAF that enforces authentication before requests reach /Operator/Search.
• Review access logs for prior unauthenticated requests to /Operator/Search and treat positive matches as potential data exposure events.

Patch Information

No vendor advisory or patch URL is listed in the NVD or referenced VulDB record at the time of publication. Operators of Das Parking Management System 6.2.0 should contact the vendor directly for a remediated build or upgrade path. Monitor the VulDB submission record for updated remediation information.

Workarounds

• Block external access to /Operator/Search at the network or proxy layer until a vendor patch is available.
• Require authentication enforcement via a reverse proxy for all /Operator/* paths.
• Disable or isolate the parking management application from the public internet if operational use does not require external reachability.

# Example nginx rule to block unauthenticated external access to the vulnerable endpoint
location /Operator/Search {
    allow 10.0.0.0/8;       # internal operator network
    deny  all;              # block all other sources
    auth_request /auth;     # require upstream auth check
    proxy_pass http://parking_backend;
