The issue is how the FTP client trusts the host from the PASV response by default. This flaw allows an attacker to set up a malicious FTP server that can trick FTP clients into connecting back to a given IP address and port. This vulnerability could lead to FTP client scanning ports, which otherwise would not have been possible.</p> <p><strong>Affected:</strong> python</p> <p>A flaw was found in Python, specifically in the FTP (File Transfer Protocol) client library in PASV (passive) mode.
