Description
A vulnerability was found in EMQ EMQX Enterprise up to 6.1.0. The impacted element is an unknown function of the component Session Handling. The manipulation results in improper authorization. It is possible to launch the attack remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
EMQX Enterprise 6.1.0 and earlier is vulnerable to denial of service due to improper session management. An authenticated attacker can connect using another user's Client ID, causing the broker to disconnect the victim's client. Client IDs are not bound to specific users, allowing cross‑user session takeover.
