CVE-2020-13931: Apache Tomee

Critical severity, CVSS 9.8. EPSS: 3.7% chance of exploitation in the next 30 days.

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, up to and including 1.7.5; from 7.0.0, up to and including 7.0.8; from 7.1.0, up to and including 7.1.3; from 8.0.0, up to and including 8.0.3; version 7.0.0 only; version 8.0.0 only
