Opened: Nov 20, 2015
Severity: 3-Major

Symptoms

document.write from window to iframe could silently fail, if page is accessed by FQDN, and Same Origin Policy restrictions were relaxed with assignment to a document.domain. The code on the page will be executed without errors, but no content will appear in iframe.

Impact

Some content could be not displayed on a page accessed through Portal Access.

Conditions

This can occur with web applications that use heavy javascript including javascript across iFrames.

Workaround

iRule workaround specific to a web application

Fix Information

Now iFrame with empty origin inherits origin value from parent window being accessed via Portal Access in the same manner as all browsers do.
