Some security issues have been reported in TURCK BL20 / BL67, which can be exploited by malicious people to bypass certain security restrictions.
The security issues are caused due to the device using certain user accounts with hardcoded credentials for the FTP service, which can potentially be exploited to gain administrative access to the device via TCP Port 21 and subsequently manipulate device communication.
