CVE-2020-13920
Medium 5.9
In plain English
A medium-severity security flaw in Apache ActiveMQ. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 4.5% (higher than 92% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
Apache ActiveMQ uses LocateRegistry.createRegistry() to create the JMX RMI registry and binds the server to the "jmxrmi" entry. It is possible to connect to the registry without authentication and call the rebind method to rebind jmxrmi to something else. If an attacker creates another server to proxy the original, and bound that, he effectively becomes a man in the middle and is able to intercept the credentials when an user connects. Upgrade to Apache ActiveMQ 5.15.12.
