[jira] Commented: (HADOOP-6151) The servlets should quote html characters

    [ https://issues.apache.org/jira/browse/HADOOP-6151?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12731727#action_12731727 ] 

Owen O'Malley commented on HADOOP-6151:
---------------------------------------

I believe the transforms should be:
  1. & -> &amp;
  2. < -> &lt;
  3. > -> &gt;
  4. ' -> &apos;
  5. "-> &quot;

As long as we do those transforms, any html that the user includes in their data will just be treated as literal text rather than html commands.

> We need to quote html characters that come from user generated data. Otherwise, all of the web ui's have cross site scripting attack, etc.
