What is Apache ActiveMQ?
Apache ActiveMQ is an open-source, multi-protocol, Java-based messaging server. It is commonly used by businesses and developers to facilitate communication between different components of software architecture via queues and topics. Given its widespread use across various industries, securing ActiveMQ installations is essential to protect sensitive data and maintain operational integrity.
Details of the CVE-2021-26117 Vulnerability
The issue in question arises from the optional LDAP login module within Apache ActiveMQ. This module could be configured to allow anonymous access to the LDAP servers. The flaw was particularly problematic because, in such configurations, the anonymous context was erroneously used to verify user passwords. Consequently, this resulted in the system failing to perform any password check under certain conditions, potentially allowing unauthorized access to the messaging system.
The versions impacted by this vulnerability include:
This vulnerability exposes various ActiveMQ configurations to potential unauthorized access, posing significant security and operational risks.
