QID 375573: RabbitMQ Server Multiple Vulnerabilities

RabbitMQ is an open source message broker software (sometimes called message-oriented middleware) that originally implemented the Advanced Message Queuing Protocol (AMQP) and has since been extended with a plug-in architecture to support Streaming Text Oriented Messaging Protocol (STOMP), Message Queuing Telemetry Transport (MQTT), and other protocols.

CVE-2021-22117 : RabbitMQ installers on Windows prior to version 3.8.16 do not harden plugin directory permissions, may allow a malicious actor can execute arbitrary code on the running RabbitMQ server by adding arbitrary plugins.
CVE-2021-22116 : 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..

QID Detection Logic:
Authenticated: On Microsoft Windows systems, the HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\RabbitMQ registry key is parsed to check for vulnerable versions of rabbitmq.

Successful exploitation of this vulnerability may allow an attacker to execute arbitrary code execution on the target system.
