Description Florence Blanc-Renaud 2022-09-15 07:04:27 UTC

+++ This bug was initially created as a clone of Bug #2124547 +++

Description of problem:

The login page on Web UI for the Identity Management exhibits strange behaviour when attempting to log in as user "root" and password specified for the "admin" default administrator user.

When attempting to log in this way, the login attempt isn't denied as it should be but the Web UI goes into a loop of trying to log in and failing, displaying only a "Loading" box on a black background.


Version-Release number of selected component (if applicable):
ipa-server-4.9.8-7.el9_0.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Set up and install ip-server with ipa-server-dns component on a RHEL9 minimal install server.
2. Open a private browsing session of Firefox or Chrome (because the login attempt gets cached)
3. Attempt to log in to the ipa web UI with username "root" and password set for the "admin" user.


Actual results:
The login attempt does not fail. The page goes into a loop reloading the page, displaying a "Loading" box and no content. The attempted credentials are cached by the browser and any attempt to open the web page results in this loading loop. Closing the tab and going to the same URL results in the same "Loading" loop. Browser cache clearing is needed for the Web UI to display the login page.

Expected results:
Login attempt should fail with 
"The password or username you entered is incorrect"
since the "root" user does not exist in IdM/ipa

Additional info:
Bug does not appear in RHEL7 IdM login page.

I am initially flagging this as a security sensitive, since I don't know if this behaviour can potentially be used for something malicious. Feel free to remove the security flag if you don't find it to be a security vulnerability.

We have handled this in upstream publicly, so this bug can be unclassified.

It should be fixed in RHEL 8.7/9.1 once they are out as part of the rebases.
