Subject [jira] [Commented] (HADOOP-13008) Add XFS Filter for UIs to Hadoop Common
Date Sun, 10 Apr 2016 22:11:25 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13008?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15234305#comment-15234305
] 

Larry McCay commented on HADOOP-13008:
--------------------------------------

So the following config would turn on XFS protection and set the global value to DENY - not
setting the value would also since it is the default:

{code}
hadoop.security.xframe-options-enabled=true
hadoop.security.xframe-options=DENY
{code}

The following additional config would override the value:

{code}
dfs.security.namenode.xframe-options=SAMEORIGIN
{code}

The filter initializer for HDFS would need to check whether it was enabled and if so what
the global value is.
Then check and see whether it is overridden by a dfs specific property.

No configured value for either would result in DENY whenever the filter is enabled.

> Cross Frame Scripting (XFS) prevention for UIs can be provided through a common servlet
filter. This filter will set the X-Frame-Options HTTP header to DENY unless configured to
another valid setting.
> There are a number of UIs that could just add this to their filters as well as the Yarn
webapp proxy which could add it for all it's proxied UIs - if appropriate.
