Background
Apache ActiveMQ is an open-source message broker that provides reliable messaging between distributed applications. It is written in Java and supports multiple protocols, including MQTT, AMQP, and STOMP. ActiveMQ uses the Java Authentication and Authorization Service (JAAS) for user authentication and authorization. However, a vulnerability in the LDAPLoginModule implementation of JAAS allows remote attackers to obtain credentials through a brute force attack.
Vulnerability Detail
The LDAPLoginModule implementation in Apache ActiveMQ 5.x before 5.10.1 allows wildcard operators in usernames, enabling attackers to perform brute force attacks to obtain valid credentials. By trying different combinations of usernames with wildcard characters, an attacker can potentially discover valid usernames and passwords, compromising the security of the system. This vulnerability was identified as CVE-2015-6524.
