--------------------------------------
Summary: Disable directory browsing in HttpServer2
Key: HADOOP-12584
URL: https://issues.apache.org/jira/browse/HADOOP-12584
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 2.8.0
Reporter: Robert Kanter
Assignee: Robert Kanter
We found a minor security issue with the Yarn Web UIs (or anything using
{{HttpServer2}}. Currently, you can list the contents of the {{/static}}
directory for the RM, NM, and JHS. This isn't a huge deal, but there are some
ways to abuse this to get access to files on the host, though it would be
pretty difficult. It's also good practice to disable directory listing on web
apps.
Here are the URLs:
- http://HOST:8088/static/
- http://HOST:19888/static/
- http://HOST:8042/static/
