CVE-2020-1929

[CVE-2020-1929] Apache Beam MongoDB IO connector disables certificate trust verification

Severity: Major Vendor: The Apache Software Foundation

Versions Affected: Apache Beam 2.10.0 to 2.16.0

Description: The Apache Beam MongoDB connector in versions 2.10.0 to 2.16.0 has an option to disable SSL trust verification. However this configuration is not respected and the certificate verification disables trust verification in every case. This exclusion also gets registered globally which disables trust checking for any code running in the same JVM.

Mitigation: Users of the affected versions should apply one of the following mitigations:

Upgrade to Apache Beam 2.17.0 or later

Acknowledgements: This issue was reported (and fixed) by Colm Ó hÉigeartaigh.
