The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:3325-1 advisory.
RabbitMQ all versions prior to 3.8.16 are prone to a denial of service vulnerability due to improper input validation in AMQP 1.0 client connection endpoint. A malicious user can exploit the vulnerability by sending malicious AMQP messages to the target RabbitMQ instance having the AMQP 1.0 plugin enabled.
(CVE-2021-22116)
RabbitMQ is a multi-protocol messaging broker. In rabbitmq-server prior to version 3.8.17, a new user being added via management UI could lead to the user’s bane being rendered in a confirmation message without proper <script>
tag sanitization, potentially allowing for JavaScript code execution in the context of the page. In order for this to occur, the user must be signed in and have elevated permissions (other user management). The vulnerability is patched in RabbitMQ 3.8.17. As a workaround, disable rabbitmq_management
plugin and use CLI tools for management operations and Prometheus and Grafana for metrics and monitoring. (CVE-2021-32718)
RabbitMQ is a multi-protocol messaging broker. In rabbitmq-server prior to version 3.8.18, when a federation link was displayed in the RabbitMQ management UI via the rabbitmq_federation_management
plugin, its consumer tag was rendered without proper <script> tag sanitization. This potentially allows for JavaScript code execution in the context of the page. The user must be signed in and have elevated permissions (manage federation upstreams and policies) for this to occur. The vulnerability is patched in RabbitMQ 3.8.18. As a workaround, disable the rabbitmq_federation_management
plugin and use CLI tools instead. (CVE-2021-32719)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
