CVE-2018-11775
TLS hostname verification when using the Apache ActiveMQ Client before 5.15.6 was missing which could make the client vulnerable to a MITM attack between a Java application using the ActiveMQ client and the ActiveMQ server.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.96%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
TLS hostname verification when using the Apache ActiveMQ Client before 5.15.6 was missing which could make the client vulnerable to a MITM attack between a Java application using the ActiveMQ client and the ActiveMQ server. This is now enabled by default.
