Subject [jira] [Commented] (HADOOP-12691) Add CSRF Filter for REST APIs to Hadoop Common
Date Sat, 16 Jan 2016 15:53:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12691?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15103238#comment-15103238

Chris Nauroth commented on HADOOP-12691:
----------------------------------------

Oops!  I just fixed this with a {{git mv}} on both trunk and branch-2.  [~sekikn], thank you
for spotting the mistake.

bq. I suspect it was applied with a wrong argument for "-p" option.

Yeah, that's the most likely explanation.  Since the patch contained only new files, there
were no conflicts, and it just assumed I was creating a new directory.

> CSRF prevention for REST APIs can be provided through a common servlet filter. This filter
would check for the existence of an expected (configurable) HTTP header - such as X-XSRF-Header.
> The fact that CSRF attacks are entirely browser based means that the above approach can
ensure that requests are coming from either: applications served by the same origin as the
REST API or that there is explicit policy configuration that allows the setting of a header
on XmlHttpRequest from another origin.
