[jira] [Commented] (YARN-10336) RM page should throw exception when command injected in RM REST API to get applications

    [ https://issues.apache.org/jira/browse/YARN-10336?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17150303#comment-17150303 ] 

Bilwa S T commented on YARN-10336:
----------------------------------

This should be handled same way as how NodesPage is handled if NodeState given is not valid. The only difference is here we catch Illegal Argument Exception thrown by "YarnApplicationState.valueOf(stateString)"  . I think we shouldn't catch exception here.

> Using a web application attacking, we see that injecting commands like ACCEPTED, FAILED and FINISHED to RM REST API does not throw an exception. Refer images.
