to 2019.4 HF6 or 2020.2 prior to 2020.2.1 HF 2.

It is, therefore, affected by an authentication bypass vulnerability. An
unauthenticated attacker can exploit this, via a specially crafted web
request, to bypass authentication and execute privileged actions.

Note that Nessus has not tested for this issue but has instead relied only on
the application's self-reported version number.");
