Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.3, the /api/backup endpoint is accessible without authentication and discloses the encryption keys required to decrypt the backup in the X-Backup-Security response header. This allows an unauthenticated attacker to download a full system backup containing sensitive data (user credentials, session tokens, SSL private keys, Nginx configurations) and decrypt it immediately. This issue has been patched in version 2.3.…

## Summary
The `/api/backup` endpoint is accessible without authentication and discloses the encryption keys required to decrypt the backup in the `X-Backup-Security` response header. This allows an unauthenticated attacker to download a full system backup containing sensitive data (user credentials, session tokens, SSL private keys, Nginx configurations) and decrypt it immediately.
## Vulnerability Details
Ein entfernter, anonymer Angreifer kann eine Schwachstelle in nginx-ui ausnutzen, um Sicherheitsvorkehrungen zu umgehen und so eine vollständige Systembackup mit sensiblen Daten offenzulegen und zu entschlüsseln.
