#1 Updated by Dominic Cleal over 4 years ago

  • Subject changed from XSS from create/update/destroy notification boxes to EMBARGOED: XSS from create/update/destroy notification boxes

#2 Updated by Dominic Cleal over 4 years ago

This appears to be coming from the popup notifications in the UI that appear when creating/updating/deleting resources. I suppose one user could create a resource with such a name and then another user could try editing or deleting it to execute the script, but when creating, a user is only going to be able to attach themselves.

The host group name is also formatted strangely in the host groups list, may be worth checking out at the same time.

(I've also seen this when deleting config groups and templates, it's a problem generally with the process_success type notifications.)

#3 Updated by Joseph Magen over 4 years ago

  • Status changed from New to Assigned

Rails automatic escapes/sanitizes text strings when saving to the db, so this is the reason of the "strange formatting"

I emailed patch.

#4 Updated by Dominic Cleal over 4 years ago

Please just attach the patch for review here, thanks.

#5 Updated by Dominic Cleal over 4 years ago

Attached is the v1 patch.

Works well, though could we escape the HTML rather than sanitizing it? Just so the actual name fully shows up.

I looked into the index name display, it's just a bug in the ancestry_helper, pretty sure it's harmless. I'll file another bug once this is unembargoed.
