- Summary
- [none]
- Details

An issue was discovered in Prosody before 0.11.9. The undocumented dialbackwithoutdialback 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).
