CVE-2021-45115: Denial-of-service possibility in ``UserAttributeSimilarityValidator``
|
|
|
|
|
=====================================================================================
|
|
|
|
|
|
|
|
|
|
:class:`.UserAttributeSimilarityValidator` incurred significant overhead
|
|
|
|
|
evaluating submitted password that were artificially large in relative to the
|
|
|
|
|
comparison values. On the assumption that access to user registration was
|
|
|
|
|
unrestricted this provided a potential vector for a denial-of-service attack.
|
|
|
|
|
|
|
|
|
|
In order to mitigate this issue, relatively long values are now ignored by
|
|
|
|
|
``UserAttributeSimilarityValidator``.
|
|
|
|
|
|
|
|
|
|
This issue has severity "medium" according to the :ref:`Django security policy
|
|
|
|
|
<security-disclosure>`.
