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.

Reconstructing the “72nd Catch” – Three Leading Theories
Theory 1: The Lost Bitcoin Wallet
In early 2013, a Prague IT worker mined Bitcoin on a laptop, then forgot it. On 4 March 2013, he recovered an old hard drive with 720 BTC (worth ~$32,400 then, millions today). He posts online: „Dnes rychly prachy – dvaasedmdesáty ulovek. Praha. 04032013 work (bitcoiny).“ The phrase “work” might be ironic – it was not salary but a side discovery.
Patch / Workaround
Avoid downloading files/directories from untrusted FTP servers.
