What is CVE-2020-13931?

The vulnerability occurs when Apache TomEE is configured to use the embedded ActiveMQ broker and the broker configuration is misconfigured, leading to an open JMX port on TCP port 1099. This port lacks authentication, exposing the management interface to unauthorized access. While a previous vulnerability attempted to address related security issues, it did not sufficiently cover this specific edge case, leaving systems vulnerable if not properly configured.

Affected Version(s)

Apache TomEE 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
