From the CVE record
An unauthenticated attacker with network access to the captive portal service of an affected device can terminate active captive portal sessions, including forcing logout of specific users or clearing all active sessions. Affected users must re-authenticate to regain access. Successful exploitation may allow termination of individual or all active captive portal sessions, causing temporary service disruption and requiring users to re-authenticate.
