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.

I need to address the request without supporting piracy. So my response should inform the user about the legal implications of sharing ISO files, suggest purchasing a physical copy, explore digital distribution options, and discuss legal emulation as a last resort. Also, perhaps mention contacting support for the game if they lost the original. I should avoid any mention of specific file-sharing sites or links. Make sure the tone is helpful but compliant with policies.
However, the user wants a "helpful text," so maybe they need guidance on how to legally access the game. Let me consider the options. The PS2 is an older console, and physical copies might be rare or expensive. Maybe they're trying to play it on an emulator, which is a common method for preserving older games. But using emulators is legal if you own a physical copy. I should mention that. Also, there's the possibility that the game is available on a digital store, but I don't think PES 2012 is on PSN anymore since it's over a decade old. winning eleven 2012 ps2 iso link
Patch / Workaround
