In short

TerraMaster NAS devices running version 4.2.29 or earlier leak the administrator password in plain text when a specially crafted web request is made. An attacker can easily retrieve the admin password remotely without needing any credentials.

Technical detail

The vulnerability exists in module/api.php endpoint (mobile/webNasIPS function) which fails to implement access controls (CWE-306) and returns the PWD field containing plaintext administrative credentials when requests include the 'TNAS' User-Agent header. Remote unauthenticated attackers can enumerate admin credentials, leading to full NAS compromise.

TerraMaster NAS 4.2.29 and earlier allows remote attackers to discover the administrative password by sending "User-Agent: TNAS" to module/api.php?mobile/webNasIPS and then reading the PWD field in the response.
