CVE-2016-0756 (opens in a new tab)How to fix?
Upgrade Debian:10 prosody to version 0.9.10-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream prosody package and not the prosody package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
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.
