Description Pedro Sampaio 2017-11-03 20:59:19 UTC 
A flaw was found in ipa where the two-factor authentication is not properly enforced for Authn/TOTP defined users.

Comment 1 Pedro Sampaio 2017-11-03 20:59:58 UTC 
Created freeipa tracking bugs for this issue:

Affects: fedora-all [bug 1509469]
Comment 2 Cedric Buissart 2021-05-24 08:07:25 UTC 
Not considered a security flaw : 
From the description, if an user is hammering too much against ipa-otpd, it may crash. This forces users to re-authenticate (using their password only, not 2nd factor).

Status:
Upstream fixes for master : 
https://pagure.io/freeipa/c/a2e8d98
https://pagure.io/freeipa/c/fe65008
https://pagure.io/freeipa/c/ab63668 (tests only)

fixed in : 
- freeipa 4.5 latest (not tagged release)
- freeipa 4.6.5
- freeipa 4.7.1
- freeipa 4.8.0

All versions of freeipa shipped in RHEL-8 and latest version of RHEL-7 are fixed.
