An issue was discovered in TitanFTP (aka Titan FTP) NextGen before 1.2.1050. There is Remote Code Execution due to a hardcoded password for the sa account on the Microsoft SQL Express 2019 instance installed by default during TitanFTP NextGen installation, aka NX-I674 (sub-issue 1). NOTE: as of 2022-06-21, the 1.2.1050 release corrects this vulnerability in a new installation, but not in an upgrade installation.

A Directory Traversal issue was discovered in the Web GUI in Titan FTP Server 2019 Build 3505. When an authenticated user attempts to preview an uploaded file (through PreviewHandler.ashx) by using a \..\..\ technique, arbitrary files can be loaded in the server response outside the root directory.
