Hello Kurt, Steve, vendors,

a security flaw was found in the XMPP Dialback protocol
implementation of jabberd2, OpenSource server implementation of the
Jabber protocols (Verify Response and Authorization Response were
not checked within XMPP protocol server to server session). A rogue
XMPP server could use this flaw to spoof one or more domains, when
communicating with vulnerable server implementation, possibly
leading into XMPP's Server Dialback protections bypass.
