RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Ivan Brkic 2022-09-06 13:16:51 UTC 
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.
Comment 1 Alexander Bokovoy 2022-09-07 12:51:37 UTC 
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.

Comment 4 Florence Blanc-Renaud 2022-09-07 15:04:07 UTC 
Note: the issue also happens on RHEL 8.6 but DOES NOT happen on RHEL 7.9 (it is related to the introduction of the patch https://pagure.io/freeipa/c/4911a3f05514a7c0ac66e4ef5004581cced8519f Prevent local account takeover which was backported to RHEL 8.6 but not to RHEL 7.9).

@security-response-team can you remove the Security keyword? The issue has already been discussed and fixed upstream.
Comment 7 Michal Polovka 2022-10-27 14:35:11 UTC 
ipa-server-4.10.0-7.el9_1.x86_64

Admin password: Secret123
Root password: BananaBreadIsTheBest123 (see the difference in length)

Logged in as user root with admin's password (see the attached screenshot), therefore marking as pre-verified:tested. Automation in progress.

The failure in unrelated test is caused by machine setup and it's not a regression.

Marking as verified.
