CVE-2024-3776
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 · uneditedThe parameter used in the login page of Netvision airPASS is not properly filtered for user input. An unauthenticated remote attacker can insert JavaScript code to the parameter for Reflected Cross-site scripting attacks.
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 confidenceNetvision airPASS login page contains a reflected XSS vulnerability where a parameter is not properly filtered, allowing unauthenticated remote attackers to inject malicious JavaScript code through the parameter for reflected Cross-site scripting attacks.

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 the productConfirm the deployed application is Netvision airPASS by checking the web interface banner, title, or login page for 'Netvision' or 'airPASS' brandingAffected if The application is Netvision airPASS
-
Check the installed versionLocate the version number in the product interface, typically found in the login page footer, about section, or in system information/settings. Compare against the affected version 2.9.0.231006Affected if The installed version is exactly 2.9.0.231006
-
Access the login pageNavigate to the airPASS web login interface, typically accessible via HTTP/HTTPS on the default management portAffected if The login page is accessible without authentication
-
Test for reflected parametersReview the login page URL and form parameters. Submit test values in query strings or form fields (such as username, redirect, or error message parameters) and observe if the input is reflected back in the response without encodingAffected if Any parameter in the login page reflects user-supplied input back in the response without proper sanitization
You are affected if the installed version is exactly 2.9.0.231006 AND the login page reflects unsanitized user input in any parameter.
Generated from the published advisory. Verify against your own configuration.
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 on all login page parameters to prevent XSS injection; validate and sanitize all user-supplied input before reflecting it back in the response.
