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 · unedited
The Kiwire Captive Portal contains an open redirection issue via the login-url parameter, allowing an attacker to redirect users to an attacker controlled website.

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 confidence

Kiwire Captive Portal has an open redirection vulnerability in the login-url parameter. Attackers can craft malicious URLs that redirect authenticated users to attacker-controlled websites, enabling phishing and credential theft attacks.

MitigationImplement strict URL validation on the login-url parameter, restricting redirects to an allowlist of trusted domains or requiring relative URLs only.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Kiwire version
    Locate the Kiwire installation and determine the exact software version number. Check system information, about page, or version file within the Kiwire application directory.
    Affected if The installed version is exactly 3.6, as this is the only version confirmed affected by CVE-2025-11190.
  2. Confirm Captive Portal module is active
    Verify that the Captive Portal feature is enabled and accessible on the Kiwire deployment. This may be confirmed through the admin interface, network configuration, or by attempting to access the captive portal login page.
    Affected if The Captive Portal is enabled and reachable, exposing the login-url parameter to user interaction.
  3. Locate the login-url parameter
    Examine the Captive Portal login page or its form submission handling to identify the login-url parameter. This parameter typically controls the post-login redirect destination.
    Affected if The login-url parameter exists and accepts user-supplied input without strict validation.
  4. Inspect redirect URL validation logic
    Review the server-side code or configuration that processes the login-url parameter to determine whether URL validation is implemented. Look for allowlist enforcement or restriction to relative URLs.
    Affected if No allowlist-based URL validation exists, or the validation allows arbitrary external domains in the login-url parameter.

A user is affected if they run Synchroweb Kiwire version 3.6 with the Captive Portal enabled and the login-url parameter accepts unvalidated external URLs.
