CVE-2025-4763
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper Neutralization of Input During Web Page Generation (XSS or 'Cross-site Scripting') vulnerability in Aida Computer Information Technology Inc. Hotel Guest Hotspot allows Reflected XSS. This issue affects Hotel Guest Hotspot: through 22012026. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceReflected XSS vulnerability in Aida Computer Technology Inc. Hotel Guest Hotspot software allows attackers to inject malicious scripts through unsanitized user input that gets reflected back in web pages. This can lead to session hijacking, credential theft, or malicious content injection for other users.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Aida Hotel Guest Hotspot is installedSearch for the application in your system installation directories or check running services for processes named 'Aida', 'HotelGuestHotspot', or similar. On Linux, check /opt or /usr/local for Aida directories. On Windows, check Program Files directories.Affected if The software is found running or installed on the system
-
Determine the installed version or build dateLocate the software's version information - check the main executable properties, a README file, or any version.txt within the installation directory. Look for a date or version number that can be compared against the 2026-01-22 threshold.Affected if The version or build date is <= 2026-01-22 or cannot be determined (assume affected)
-
Verify the web interface is accessibleIdentify which port the Hotel Guest Hotspot web interface runs on (commonly ports 80, 443, 8080, or 8443). Use a browser or curl to access the login or splash page of the hotspot portal.Affected if The web interface is reachable and responds to HTTP/HTTPS requests
-
Test for reflected XSS in input fieldsSubmit a benign XSS probe string like <script>alert(1)</script> or <img src=x onerror=alert(1)> in common input fields (username, email, room number, WiFi access code). Observe whether this string is returned verbatim in the page response without encoding or escaping.Affected if The malicious script tags are reflected back in the response without sanitization
A user is affected if the Aida Hotel Guest Hotspot software is installed with a version or build date <= 2026-01-22, exposes a web interface, and user input is reflected back in pages without encoding.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper input validation and output encoding/escaping on all user-supplied data before rendering in web pages. Since the vendor has not responded to disclosure attempts, consider isolating the application via web application firewall or network segmentation until a fix is available.
