CVE-2025-65132: Hotel Management PHP XSS Vulnerability

CVE-2025-65132 Overview

CVE-2025-65132 is a Cross-Site Scripting (XSS) vulnerability affecting alandsilva26 hotel-management-php version 1.0. The vulnerability exists in the /public/admin/edit_room.php endpoint, which allows an attacker to inject and execute arbitrary JavaScript code via the room_id GET parameter. This reflected XSS vulnerability can be exploited to steal session cookies, perform actions on behalf of authenticated users, or redirect victims to malicious websites.

Critical Impact

Attackers can inject malicious JavaScript through the room_id parameter, potentially compromising administrator sessions and gaining unauthorized access to hotel management functions.

Affected Products

• alandsilva26 hotel-management-php version 1.0
• Web applications utilizing the vulnerable /public/admin/edit_room.php endpoint

Technical Details for CVE-2025-65132

Vulnerability Analysis

This vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation), commonly known as Cross-Site Scripting. The affected component fails to properly sanitize user-supplied input in the room_id GET parameter before reflecting it back in the HTTP response. When a victim clicks on a maliciously crafted URL containing JavaScript code in the room_id parameter, the script executes within the context of the victim's browser session.

The attack requires user interaction, as a victim must be enticed to click on a specially crafted link. However, once executed, the injected JavaScript runs with the same privileges as the target web application, potentially allowing attackers to steal authentication tokens, modify page content, or perform administrative actions on behalf of the authenticated user.

Root Cause

The root cause of this vulnerability is insufficient input validation and output encoding in the edit_room.php file. The room_id GET parameter is directly incorporated into the page output without proper sanitization or HTML entity encoding. This allows attackers to break out of the expected data context and inject executable script content.

Attack Vector

The attack vector is network-based, requiring an attacker to craft a malicious URL and convince a victim to visit it. The typical attack scenario involves social engineering techniques such as phishing emails or malicious links embedded in forums or social media. When an authenticated administrator clicks on the crafted link, the injected JavaScript executes in their browser, potentially exposing sensitive session data or enabling unauthorized administrative actions.

The vulnerability can be exploited by appending malicious JavaScript to the room_id parameter. For example, an attacker could craft a URL containing script tags or event handlers that execute when the page is rendered. Technical details and proof-of-concept information are available in the GitHub Security Advisory.

Detection Methods for CVE-2025-65132

Indicators of Compromise

• Unusual URL patterns containing JavaScript code or HTML tags in the room_id parameter
• Web server logs showing requests to /public/admin/edit_room.php with encoded script payloads
• User reports of unexpected browser behavior or redirects when accessing the hotel management interface
• Authentication anomalies following visits to the vulnerable endpoint

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block XSS payloads in GET parameters
• Monitor web server access logs for suspicious patterns such as <script>, javascript:, or encoded variants in the room_id parameter
• Deploy Content Security Policy (CSP) headers with reporting capabilities to detect inline script execution attempts
• Use browser-based XSS auditor logging to identify attempted attacks

Monitoring Recommendations

• Enable verbose logging for the /public/admin/ directory to capture all parameter values
• Configure SIEM alerts for URL patterns matching common XSS attack signatures
• Implement real-time monitoring for unusual administrative session activity following external link referrals
• Review access logs regularly for requests originating from suspicious referrer URLs

How to Mitigate CVE-2025-65132

Immediate Actions Required

• Restrict access to the /public/admin/edit_room.php endpoint to trusted IP addresses only
• Implement input validation to ensure room_id contains only numeric values
• Apply output encoding using htmlspecialchars() or equivalent functions when rendering user input
• Deploy a Web Application Firewall with XSS protection rules as an interim measure

Patch Information

At the time of publication, no official patch has been released by the maintainer. Organizations using this software should implement the workarounds described below and monitor the GitHub Security Advisory for updates. Consider migrating to an actively maintained hotel management solution if patches are not forthcoming.

Workarounds

• Apply input validation to enforce that room_id accepts only integer values using intval() or similar type casting
• Implement output encoding using htmlspecialchars($room_id, ENT_QUOTES, 'UTF-8') before rendering the parameter value
• Add Content Security Policy headers to prevent inline script execution: Content-Security-Policy: script-src 'self'
• Restrict administrative interface access via .htaccess rules or network-level firewall controls

# Apache .htaccess configuration to restrict admin access
<Directory "/public/admin/">
    # Restrict to specific IP addresses
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
    
    # Deny all other access
    Require all denied
</Directory>
