CVE-2025-5184: Vacation Rental Platform Disclosure Flaw

CVE-2025-5184 Overview

CVE-2025-5184 is an information disclosure vulnerability in the Summer Pearl Group Vacation Rental Management Platform versions up to and including 1.0.1. The flaw resides in the HTTP Response Header Handler component, where manipulation of an unspecified function leaks sensitive information to remote attackers. The vendor has released version 1.0.2 to remediate the issue. The weakness is classified under [CWE-200] Exposure of Sensitive Information to an Unauthorized Actor. Attackers can exploit the vulnerability remotely over the network with low privileges and without user interaction.

Critical Impact

Authenticated remote attackers can extract sensitive information through manipulated HTTP response headers, exposing data that supports reconnaissance and follow-on attacks against the vacation rental management platform.

Affected Products

• Summer Pearl Group Vacation Rental Management Platform versions up to 1.0.1
• Deployments exposing the HTTP Response Header Handler component to untrusted networks
• Tenants running unpatched installations prior to release 1.0.2

Discovery Timeline

• 2025-05-26 - CVE-2025-5184 published to the National Vulnerability Database

Technical Details for CVE-2025-5184

Vulnerability Analysis

The vulnerability stems from improper handling of HTTP response headers within the Summer Pearl Group Vacation Rental Management Platform. An unidentified function in the HTTP Response Header Handler returns information that should not be exposed to the requesting client. Attackers reaching the affected endpoint receive header content disclosing sensitive application data.

The issue maps to [CWE-200], which addresses the exposure of sensitive information to actors that are not explicitly authorized to access that data. Exploitation requires only low-privilege authenticated access and no user interaction, making the attack practical against internet-facing instances. The impact is limited to confidentiality, with no direct effect on integrity or availability of the platform.

While the EPSS data places near-term exploitation probability low, information disclosure flaws frequently serve as preparatory steps. Disclosed header data can reveal session identifiers, internal hostnames, framework versions, or platform configuration that accelerates subsequent intrusion stages.

Root Cause

The root cause is insufficient sanitization of data emitted in HTTP response headers. The handler component appends or echoes application state into outbound headers without verifying whether the requesting principal is authorized to receive it. This pattern typically results from debug headers, verbose error metadata, or session-bound values being added globally to responses.

Attack Vector

The attack vector is fully remote over the network. An authenticated attacker with low privileges issues a crafted HTTP request to the vulnerable endpoint and inspects the returned response headers. No user interaction or social engineering is required. The disclosed information can then be reused to target other tenants, escalate privileges, or pivot into adjacent systems.

Detection Methods for CVE-2025-5184

Indicators of Compromise

• Unusual volumes of HTTP HEAD or GET requests against the vacation rental platform originating from a single source, particularly authenticated sessions enumerating multiple endpoints
• Outbound HTTP responses containing unexpected custom headers, debug fields, or internal identifiers from the affected application
• Authenticated low-privilege accounts accessing endpoints outside their normal functional scope

Detection Strategies

• Inspect web server and reverse proxy logs for response headers that include application internals, session metadata, or stack identifiers
• Compare deployed platform versions against the fixed release 1.0.2 to identify exposed instances
• Correlate authentication events with anomalous request patterns to identify reconnaissance against the HTTP Response Header Handler

Monitoring Recommendations

• Forward web application access logs and response header captures to a centralized analytics platform for retention and query
• Establish baselines for normal header content per endpoint and alert on deviations
• Monitor authenticated user behavior for enumeration patterns consistent with information harvesting

How to Mitigate CVE-2025-5184

Immediate Actions Required

• Upgrade Summer Pearl Group Vacation Rental Management Platform to version 1.0.2 or later as published on the vendor releases page
• Inventory all internet-facing deployments and restrict administrative endpoints to trusted networks until patching completes
• Rotate credentials, session tokens, and API keys that may have been exposed through leaking response headers
• Audit authenticated user accounts for unusual activity that may indicate prior reconnaissance

Patch Information

The vendor addressed the vulnerability in version 1.0.2. Patch and release notes are available at the Summer Pearl Group Releases page. Operators running any release up to and including 1.0.1 must upgrade to eliminate exposure.

Workarounds

• Place a reverse proxy in front of the application to strip or normalize sensitive response headers before they reach clients
• Restrict access to the platform using network access controls, VPNs, or IP allowlists until the upgrade is deployed
• Reduce authenticated user privileges to the minimum required, limiting the attack surface exposed to low-privilege accounts

# Example NGINX configuration to strip sensitive response headers
location / {
    proxy_pass http://spgpm_backend;
    proxy_hide_header X-Powered-By;
    proxy_hide_header X-Debug-Token;
    proxy_hide_header X-Application-Context;
    proxy_hide_header Server;
    add_header X-Content-Type-Options "nosniff" always;
