CVE-2020-14348 in AMQ Online
Summary
by MITRE
It was found in AMQ Online before 1.5.2 that injecting an invalid field to a user's AddressSpace configuration of the user namespace puts AMQ Online in an inconsistent state, where the AMQ Online components do not operate properly, such as the failure of provisioning and the failure of creating addresses, though this does not impact upon already existing messaging clients or brokers.

The vulnerability identified as CVE-2020-14348 affects AMQ Online versions prior to 1.5.2, representing a significant configuration management flaw within the Red Hat AMQ Online messaging platform. This issue manifests when an invalid field is injected into a user's AddressSpace configuration within the user namespace, creating a state of operational inconsistency that fundamentally undermines the platform's reliability and functionality. The vulnerability resides in the platform's handling of malformed configuration inputs, where the system fails to properly validate or reject invalid field specifications during the AddressSpace creation or modification processes.
The technical flaw stems from inadequate input validation mechanisms within the AMQ Online controller components responsible for managing AddressSpace configurations. When an invalid field is introduced into the configuration, the system enters a degraded operational state where core provisioning functions become non-functional, preventing the successful creation of new addresses and address spaces. This behavior directly violates the principles of robust error handling and input validation that are fundamental to secure system design. The vulnerability operates at the configuration management layer, where the platform's reconciliation loops fail to properly detect and handle malformed inputs, leading to cascading failures in the operational workflow.
The operational impact of this vulnerability extends beyond simple configuration errors, as it fundamentally compromises the platform's ability to provision new messaging resources while leaving existing messaging clients and brokers unaffected. This partial impact creates a dangerous operational scenario where administrators may believe the system is functioning normally while critical provisioning capabilities are silently disabled. The inconsistency state can persist until manual intervention occurs, potentially leading to extended periods of reduced functionality and operational disruption. This vulnerability particularly affects environments where automated provisioning and dynamic address creation are critical components of the messaging infrastructure, as the failure to create new addresses can halt application deployment workflows and service provisioning processes.
From a cybersecurity perspective, this vulnerability aligns with CWE-20: Improper Input Validation, which addresses the lack of proper validation of input data that can lead to system instability and unexpected behavior. The issue also relates to ATT&CK technique T1210: Exploitation of Remote Services, as it represents an avenue for attackers to potentially disrupt service availability through configuration manipulation. Organizations using AMQ Online should prioritize immediate patching to version 1.5.2 or later, which includes enhanced input validation mechanisms and improved error handling for malformed AddressSpace configurations. Additionally, implementing monitoring solutions that can detect configuration inconsistencies and automated alerting for provisioning failures would provide early detection capabilities. The vulnerability underscores the importance of robust configuration management practices and demonstrates how seemingly minor input validation gaps can result in significant operational disruptions within complex messaging platforms.
