The FTP service in QNAP iArtist Lite before 1.4.54, as distributed with QNAP Signage Station before 2.0.1, has hardcoded credentials, which makes it easier for remote attackers to obtain access via a session on TCP port 21.
Add your gear to cvedb and we'll alert you only when qnap ships something exploited.
