> When browsing to the datanode at /browseDirectory.jsp, if a path with HTML
> characters is requested, the resulting error page echos back the input
> unquoted.
> Example:
> http://localhost:50075/browseDirectory.jsp?dir=/<xss>&go=go&namenodeInfoPort=50070&nnaddr=localhost%3A9000
> Writes an input element as part of the response:
> <input name="dir" type="text" width="50" id"dir" value="/<xss>">
> - The value of the "value" attribute is not quoted.
> - An = must follow the "id" attribute name.
> - Element "input" should have a closing tag.
> The output should be something like:
> <input name="dir" type="text" width="50" id="dir" value="/<xss>"/>
> In addition, if one creates a directory:
> hdfs dfs -put '/some/path/to/<xss>'
> Then browsing to the parent of directory '<xss>' prints unquoted HTML in the
> directory names.
