Description Dhananjay Arunesh 2019-11-12 09:07:55 UTC
A vulnerability was found in Pallets Werkzeug before 0.15.3, when used with Docker, has insufficient debugger PIN randomness because Docker containers share the same machine id.

Comment 10 Yadnyawalk Tale 2020-02-24 14:11:03 UTC
Statement:

While Red Hat Quay contains a vulnerable version of python-werkzeug in the quay container image, use of the debug feature is not recommended in any upstream or downstream documentation. A user of Red Hat Quay would have to enable python-werkzeug debugging before Red Hat Quay became vulnerable.

This issue did not affect the versions of python-werkzeug as shipped with Red Hat Update Infrastructure as they did not include support for PIN based authentication. The same is true for the versions of python-werkzeug as shipped with Red Hat Enterprise Linux 8.

Red Hat Satellite ships vulnerable python-werkzeug, however, it is not affected because it uses python-werkzeug as a dependency of python-flask required by Crane component and therefore package does not get invoked directly.
