Hi John,

> I guess my question is whether this should be reported as a bug/vulnerability

No, it is not a security vulnerability. Ambari-UI is trying to resize itself to 
fit the size of its view-UI... that is the only thing that will be broken. It 
breaks in your case because Ambari-UI from one domain is trying to look into UI 
of another domain (Job History server). It was not designed to contain content 
from other domains. So basically what we are saying is that the iframe should 
only contain content from ambari-server's domain for it to work properly.

I do not think it should matter where the link is in the document hierarchy... 
it should behave the same way. Maybe there is something else happening when it 
is at a different location


Hope that helps.

That is what I am doing now. I guess my question is whether this should be 
reported as a bug/vulnerability because it still follows the link in this 
setup, which like you said is a security vulnerability. If I were to put the 
link within the body tag (not in the bootstrap table), it does not follow the 
link. I feel that this is what should happen when it is in the bootstrap table 
rather than still following the link and changing the iframe height.

Hi John,

It is generally intended that the views-area of Ambari-Web UI will show only 
views. Attempting to show some other website in there will result in Ambari-Web 
hitting security exception (as you have), due to ambari-web javascript trying 
to change some other website - 
https://developer.mozilla.org/en-US/docs/Web/Security/Same-origin_policy



It might be better to open your Job link in another window/tab using 
'target="_blank"'.

Regards,

Srimanth

Subject: Ambari Views Error

Hi, I am developing a Ambari View in which one component of it is to provide 
links to jobs on the Job History Server. When the link is clicked, the iframe 
that held the view now goes to the Job History Server and throws the following 
error in the browser console.

Uncaught SecurityError: Blocked a frame with origin <Ambari View> from 
accessing a frame with origin <Job History Server> Protocols, domains, and 
ports must match. step9_view.js:1
App.MainViewsDetailsView.Em.View.extend.resizeFunction step9_view.js:1
(anonymous function)

The link is inserted into a bootstrap tblflat element row from which it can be 
clicked.

Also, after the link is clicked and the iframe opens the Job History Server, 
the iFrame height attribute is set to auto which causes the height to shrink 
between 100 and 200 pixels. Is this the correct action, or should the iframe be 
prevented from following the link in the first place? What is the expected 
behavior?
