CyberRota Analysis

AI-Generated

RabbitMQ versions prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6 are vulnerable due to a lack of authorization checks on passive queue.declare and exchange.declare operations, enabling authenticated users to enumerate queue and exchange names as well as access message and consumer counts. This vulnerability could lead to information disclosure, potentially aiding in further attacks against the system. Organizations using affected versions of RabbitMQ should prioritize upgrading to the patched versions to mitigate this risk.

Original NVD Description

RabbitMQ is a messaging and streaming broker. Prior to 3.13.15, 4.0.20, 4.1.11, and 4.2.6, RabbitMQ does not perform authorization checks on passive queue.declare and exchange.declare AMQP 0-9-1 operations, allowing any authenticated user who can connect to a virtual host to enumerate queue and exchange names and read queue message and consumer counts. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6.
