CVE-2016-0756: Input Validation
First published: Fri Jan 29 2016(Updated: )
The generate_dialback function in the mod_dialback module in Prosody before 0.9.10 does not properly separate fields when generating dialback keys, which allows remote attackers to spoof XMPP network domains via a crafted stream id and domain name that is included in the target domain as a suffix.
