(Dub) 7 : A Long-Awaited Revenge Details

This advisory discloses a vulnerability within the FTP client in AceFTP. When exploited, this vulnerability allows an anonymous attacker to write files to arbitrary locations on a Windows user's system.

The FTP client does not properly sanitise filenames containing directory traversal sequences (forward-slash) that are received from an FTP server in response to the LIST command.

An example of such a response from a malicious FTP server is shown below.


Response to LIST (forward-slash):

-rw-r--r--    1 ftp      ftp            20 Mar 01 05:37 /../../../../../../../../../testfile.txt\r\n
 

By tricking a user to download a directory from a malicious FTP server that contains files with fowward-slash directory traversal sequences in their filenames, it is possible for the attacker to write files to arbitrary locations on a user's system with privileges of that user. An attacker can potentially leverage this issue to write files into a user's Windows Startup folder and execute arbitrary code when the user logs on.
