There is an open redirect vulnerability in Titan FTP server 19.0 and below. Users are redirected to any target URL.

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.

Directory traversal vulnerability in the web interface in Titan FTP Server before 10.40 build 1829 allows remote attackers to obtain the property information of an arbitrary home folder via a Properties action with a .. (dot dot) in the src parameter.

Directory traversal vulnerability in the web interface in Titan FTP Server before 10.40 build 1829 allows remote attackers to list all usernames via a Go action with a .. (dot dot) in the search-bar value.

Directory traversal vulnerability in the web interface in Titan FTP Server before 10.40 build 1829 allows remote attackers to copy an arbitrary user's home folder via a Move action with a .. (dot dot) in the src parameter.

Directory traversal vulnerability in TitanFTPd in South River Technologies Titan FTP Server 8.10.1125, and probably earlier versions, allows remote authenticated users to read arbitrary files, determine file size, via "..//" sequences in the xcrc command.

Directory traversal vulnerability in TitanFTPd in South River Technologies Titan FTP Server 8.10.1125, and probably earlier versions, allows remote authenticated users to read or delete arbitrary files via "..//" sequences in a COMB command.

Titan FTP Server 6.26 build 630 allows remote attackers to cause a denial of service (CPU consumption) via the SITE WHO command.

Heap-based buffer overflow in Titan FTP Server 6.05 build 550 allows remote attackers to execute arbitrary code via a long DELE command.

Multiple heap-based buffer overflows in the (1) FTP service and (2) administration service in Titan FTP Server 6.0.5.549 allow remote attackers to cause a denial of service (daemon hang) and possibly execute arbitrary code via a long command. NOTE: the USER and PASS commands for the FTP service are covered by CVE-2008-0702.

Multiple heap-based buffer overflows in Titan FTP Server 6.03 and 6.0.5.549 allow remote attackers to cause a denial of service (daemon crash or hang) and possibly execute arbitrary code via a long argument to the (1) USER or (2) PASS command, different vectors than CVE-2004-1641.

Titan FTP Server version 3.01 build 163, and possibly other versions before build 169, allows remote authenticated users to cause a denial of service (crash) by disconnecting from the system during a "LIST -L" command, which causes Titan to access an invalid socket.
