Description Jan Lieskovsky 2012-08-22 15:21:02 UTC

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.
