Advisory Details:

High-Tech Bridge SA Security Research Lab has discovered vulnerability in TurboFTP Client which could be exploited to execute arbitrary code on vulnerable system.


1) Directory Traversal Vulnerability in TurboFTP Client

The vulnerability exists due to insufficient sanitation of the downloaded filename. A remote attacker controlling an FTP server can trick user into downloading file with specially crafted filename, containing directory traversal sequences (e.g. "..\..\..\..\..\..\..\somefile.exe") and write it into arbitrary locations on target system. Successful exploitation might allow remote code execution but requires that victim uses TurboFTP client to connect to FTP server and download a malicious file.


Solution:
Currently we are not aware of any vendor-supplied patches or other solutions. The vendor was contacted in accordance to our Vendor Notification Policy but we didn't get any answer or feedback.
