Urgent: Assistance Needed - oVirt Host Unresponsive
by Sachendra Shukla
HI Team,
I am writing to inform you about an issue we are currently facing with our
oVirt host. Unfortunately, the host has become unresponsive, and our
attempts to place it in maintenance mode have been unsuccessful.
Additionally, when checking the VDSM status, we encountered an error.
Here is a snapshot for your reference:

would like to change it. Is there any way how to do it without redeploy
hosted engine ?
Thank you for any help.

Internal pentest result : Ovirt-engine authentication bypass
by Jirka Simon
Hello ovirt comunity.
We had an internal pentest here and one finding is
*Ovirt-engine authentication bypass.*
Ovirt-engine, as deployed on ovirtm.XXX.XXX.cz, contains an
authentication bypass. It is
possible to directly call the CreateUserSessionCommand using runAction
exposed by /ovirt-
engine/webadmin/GenericApiGWTService.
*This action explicitly enables everyone to call it:*
```/
@Override
protected boolean isUserAuthorizedToRunAction() {
return true;
}
/```
The behavior of this call differs based on the
ENGINE_SSO_ENABLE_EXTERNAL_SSO configuration
option:
```
/boolean externalSsoEnabled =
EngineLocalConfig.getInstance().getBoolean("ENGINE_SSO_ENABLE_EXTERNAL_SSO");
DbUser dbUser = externalSsoEnabled ?
dbUserDao.getByUsernameAndDomain(params.getPrincipalName(), authzName) :
dbUserDao.getByExternalId(authzName, params.getPrincipalId());/
```
If this option is enabled, usernames are used to locate users. If it's
disabled, the externalId
(which seems to be a randomly generated GUID) is used to locate users.
If the specified user exists, a session is returned for the user. If the
specified user doesn't exist,
the user is created in the system. However, the user doesn't get
assigned any group membership
or rights, therefore the session creation fails because of the missing
Login right.
The attempt to modify the users table can be seen in the SQL error
message when attempting to
use a null value for the username (as the endpoint uses GWT, the payload
is mostly unreadable):
```
/POST /ovirt-engine/webadmin/GenericApiGWTService HTTP/1.1
Host: ovirtm.xxx.xxx.cz

```
Fortunately, in our deplyoment the ENGINE_SSO_ENABLE_EXTERNAL_SSO
configuration was
set to false, so to create a session for the admin it would be necessary
to know the admin's user
externalId. However, as this is not the default configuration, it is
possible that a later
reinstallation could change the value. Still, it was possible to create
users in the system without
any authentication.
What is the best way to report this security issue?
Thank you

hosted-engine --deploy fails, apparently due to not finding storage pool
by iucounu＠gmail.com
Hi,
I'm trying to deploy a self hosted engine, and it gets to 'Wait for the host to be up' and then fails about 20mins later. Checking the hosted engine setup log, the failure seems to be to do with a storage pool not being found (see error below). Is this error referring to the storage pool that the hosted engine will use? The setup script does not ask me what kind of storage I want to use, or the path for it, does it auto detect this? The host I am running the engine setup on is part of a gluster cluster, which I have provisioned for this purpose. Do I need to edit a file somewhere to specify this, or is there something else I need to do (permissions etc)? The hosted engine VM itself comes up fine, and I can get a console on it via virsh.
Thanks for any help,
kind regards,
Cam

Unable to upload images
by avegab＠indra.es
Hello friends! I can't upload images; when I click on test connection, I encounter the certificate issue. I used to be able to upload images without any problem, but this issue started when I updated the certificates of the Hosts and reinstalled one of the Hosts so it could also deploy the engine. I am sure that the certificate is registered in the browser. Could you help me? Thank you.
