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
A vulnerability in the social login configuration option for the guest users of Cisco Business Wireless Access Points (APs) could allow an unauthenticated, adjacent attacker to bypass social login authentication. This vulnerability is due to a logic error with the social login implementation. An attacker could exploit this vulnerability by attempting to authenticate to an affected device. A successful exploit could allow the attacker to access the Guest Portal without authentication.

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

This is a logic error vulnerability in the social login implementation for guest users on Cisco Business Wireless Access Points. An unauthenticated, adjacent attacker can bypass social login authentication entirely and access the Guest Portal without valid credentials. The vulnerability stems from improper handling of the social login configuration option.

MitigationDisable the social login feature for guest users on affected Cisco Business Wireless APs until a vendor patch is available. Verify all guest network access controls and monitor for unauthorized portal access.

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 Cisco Business AP model
    Access the AP management interface or CLI and retrieve the hardware model identifier (e.g., CBW-140AC, CBW-141ACM, CBW-145AC, CBW-150AX, CBW-151AXM, CBW-240AC)
    Affected if The model is one of: 140ac, 141acm, 142acm, 143acm, 145ac, 150ax, 151axm, or 240ac
  2. Check the installed firmware version
    Navigate to the web interface Dashboard or use CLI command 'show version' to retrieve the firmware version number
    Affected if The firmware version is less than 10.8.1.0, or exactly 10.4.2 (for 150ax and 151axm models)
  3. Verify if social login is enabled for guest users
    In the AP web interface, go to Guest Portal settings or Social Login configuration section and check whether any social identity provider (Facebook, Google, etc.) is enabled for guest authentication
    Affected if Social login feature is turned on and configured for the guest portal
  4. Confirm guest portal is active
    Check the wireless network configuration to verify that a guest SSID with guest portal authentication is enabled and operational
    Affected if A guest portal with social login as the authentication method is actively configured

You are affected if you run an affected AP model with a vulnerable firmware version AND have the guest portal social login feature enabled.
