CWE-295  (opens in a new tab)

How to fix?

Upgrade Alpine:3.18 prosody to version 0.11.9-r0 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 Alpine. See How to fix? for Alpine:3.18 relevant fixed versions and status.

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).
