-----------------------------------
Summary: Ozone: Enable XFrame options for KSM/SCM web ui
Key: HDFS-12693
URL: https://issues.apache.org/jira/browse/HDFS-12693
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Affects Versions: HDFS-7240
Reporter: Elek, Marton
Assignee: Elek, Marton
According to the discussion about security checklist on dev list I started to
check the security features of the existing HttpServer2 and found that by
default the XFrame option headers are disabled. This patch enables it by
default for SCM/KSM server similar to the Namenode/Datanode webui.
(Note: Even if the only form on the SCM/KSM ui-s is the standard LogLevel form,
I think it's a good practice to enable it by default.)
Test:
Without the patch (clean build, SCM ui):
{code}
curl -v localhost:9876/jmx -o /dev/null
* TCP_NODELAY set
* Connected to localhost (::1) port 9876 (#0)
> GET /jmx HTTP/1.1
> Host: localhost:9876
> User-Agent: curl/7.55.1
> Accept: */*
>
< HTTP/1.1 200 OK

{code}
With the patch:
{code}
curl -v localhost:9876/jmx -o /dev/null
* Connected to localhost (::1) port 9876 (#0)
> GET /jmx HTTP/1.1
> Host: localhost:9876
> User-Agent: curl/7.55.1
> Accept: */*

< Pragma: no-cache
< Content-Type: application/json; charset=utf8
< X-FRAME-OPTIONS: SAMEORIGIN
< Access-Control-Allow-Methods: GET
< Access-Control-Allow-Origin: *
< Transfer-Encoding: chunked
{code}
Note: X-FRAME-OPTIONS header exists at the second case.
