Subject: CVE-2020-13931 Apache TomEE - Incorrect config on JMS Resource
Adapter can lead to JMX being enabled
Severity: High
Vendor: The Apache Software Foundation
Versions Affected:
Apache TomEE 8.0.0-M1 - 8.0.3
Apache TomEE 7.1.0 - 7.1.3
Apache TomEE 7.0.0-M1 - 7.0.8
Apache TomEE 1.0.0 - 1.7.5
Description:
If Apache TomEE 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.
Mitigation:
- Upgrade to TomEE 7.0.9 or later
- Upgrade to TomEE 7.1.4 or later
- Upgrade to TomEE 8.0.4 or later
Ensure the correct VM broker name is used consistently across the resource
adapter config.
