Description

RabbitMQ is a messaging and streaming broker. From 3.13.0 until 3.13.15, 4.0.20, 4.1.11, and 4.2.6, the Web STOMP WebSocket handler enforced neither max_frame_size nor login_timeout before authentication, allowing an unauthenticated client to keep a connection alive with a slow stream of small frames and accumulate unbounded pre-authentication state. The rabbitmq_web_stomp plugin must be enabled, and no authentication is required to reach the vulnerable path. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.

Affected configurations

• broadcom rabbitmq server (>= 3.13.0 < 3.13.15) • broadcom rabbitmq server (>= 4.0.0 < 4.0.20) • broadcom rabbitmq server (>= 4.1.0 < 4.1.11) • broadcom rabbitmq server (>= 4.2.0 < 4.2.6)
