[jira] [Commented] (WW-5268) Add configuration option to exempt classes from OGNL package exclusions

["Yasser Zamani (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/WW-5268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17689295#comment-17689295 ] 

Yasser Zamani commented on WW-5268:
-----------------------------------

Thanks for the PR but typically you wouldn't use those classes directly in an OGNL expression. If you really need it for example instead of "System.exit()" OGNL expression, define a method in your action as below:

{code:java}
Class MyAction {

public String myExit()
{
    return System.exit();
}

}
{code}

and then use "myExit()" in your OGNL expression String.

> It is currently possible to exclude packages from OGNL evaluation using `struts.excludedPackageNamePatterns` and `struts.excludedPackageNames`.
> There may exist a scenario where you wish to have certain packages excluded/blocklisted by default, but exempt specific classes from these packages that have been assessed to be safe.
