Subject [jira] [Reopened] (DERBY-6810) Add regression tests for XXE vulnerability
Date Thu, 18 Jun 2015 04:32:00 GMT

     [ https://issues.apache.org/jira/browse/DERBY-6810?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Bryan Pendleton reopened DERBY-6810:

After further study, I realize that the new tests in XMLXXETest
exercise the built-in Derby XML datatype, but do not exercise
the XmlVTI.

Since the XmlVTI also creates a XML Parser and calls it, it
may also be vulnerable to XXE attacks, and so we need to
test it, as well.

Re-opening the issue because we have more tests to write.

> We should add some regression tests demonstrating that
> Derby is no longer vulnerable to an XXE assault.
> One possibility would be to have a example using a local
> file disclosure.
> Another possibility would be to have example based on the
> well-known "Billion Laughs" denial of service attack.
