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
Cisco Unified Wireless Network (UWN) Solution 7.x before 7.0.98.0 on 4404 series controllers does not properly implement the WEBAUTH_REQD state, which allows remote attackers to bypass intended access restrictions via WLAN traffic, aka Bug ID CSCtb75305.

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

The Cisco Unified Wireless Network (UWN) Solution 7.x before 7.0.98.0 on 4404 series controllers fails to properly implement the WEBAUTH_REQD state, which is designed to enforce web-based authentication before granting network access. This implementation flaw allows remote attackers to bypass intended access restrictions by sending WLAN traffic directly without completing the required web authentication process.

MitigationUpgrade Cisco 4404 series wireless controllers to UWN version 7.0.98.0 or later to properly enforce the WEBAUTH_REQD state. Until upgraded, consider implementing additional network segmentation or VLAN isolation to limit exposure.

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 the wireless controller model
    Log into the Cisco Wireless LAN Controller CLI and run 'show inventory' or check the controller hardware to confirm it is a 4404 series controller.
    Affected if The device is a Cisco 4404 series wireless controller.
  2. Check the installed UWN software version
    Log into the Cisco Wireless LAN Controller CLI and run 'show version' to display the software version. Compare the version number to the affected range (7.0 through versions before 7.0.98.0).
    Affected if The software version is 7.0.x where x is less than 98, or specifically 7.0.x versions prior to 7.0.98.0.
  3. Verify WEBAUTH_REQD is configured for WLANs
    Log into the Cisco Wireless LAN Controller CLI and run 'show wlan summary' to list all WLANs. Then run 'show wlan <wlan_id>' for each WLAN to check the security policy. Look for entries showing 'WebAuth' as the authentication type.
    Affected if Any WLAN is configured to use WEBAUTH_REQD (web-based authentication) as the access control method.
  4. Confirm the vulnerability is exploitable
    Attempt to send WLAN traffic from a client without completing web authentication. If network access is granted without the web authentication page appearing, the vulnerability is present.
    Affected if Network access is granted without the web authentication process completing, bypassing the WEBAUTH_REQD state.

A user is affected if they have a Cisco 4404 series controller running UWN software version 7.0.x before 7.0.98.0 with WLANs configured using WEBAUTH_REQD, and traffic can bypass web authentication.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Cisco 4404 series wireless controllers to UWN version 7.0.98.0 or later to properly enforce the WEBAUTH_REQD state. Until upgraded, consider implementing additional network segmentation or VLAN isolation to limit exposure.

Recommended fix High confidence

Unified Wireless Network Solution Software 7.0.98.0 or later

  1. Download the Cisco Unified Wireless Network Solution Software version 7.0.98.0 or later from the Cisco website
  2. Access the Cisco 4404 series wireless controller via console, SSH, or web interface
  3. Back up the current controller configuration
  4. Upload the new software version to the controller
  5. Reboot the controller to apply the new software
  6. Verify the controller is running version 7.0.98.0 or later using 'show version' command
  7. Confirm the WEBAUTH_REQD state is now properly enforced on WLAN traffic
