Description

If Apache TomEE 8.0.0-M1 - 8.0.3, 7.1.0 - 7.1.3, 7.0.0-M1 - 7.0.8, 1.0.0 - 1.7.5 is configured to use the embedded ActiveMQ broker, and the broker config is misconfigured, a JMX port is opened on TCP port 1099, which does not include authentication. CVE-2020-11969 previously addressed the creation of the JMX management interface, however the incomplete fix did not cover this edge case.

Affected products

Apache TomEE: from 1.0.0 through 1.7.5; from 7.0.0 through 7.0.8; from 7.1.0 through 7.1.3; from 8.0.0 through 8.0.3; 7.0.0-m1, 7.0.0-m2, 7.0.0-m3, 8.0.0-m1
