CVE-2021-32919 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:22.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream prosody package and not the prosody package as distributed by Ubuntu.
An issue was discovered in Prosody before 0.11.9. The undocumented dialback_without_dialback option in mod_dialback enables an experimental feature for server-to-server authentication. It does not correctly authenticate remote server certificates, allowing a remote server to impersonate another server (when this option is enabled).
