Descripción
*** Pendiente de traducción *** The ftpcp() function in Lib/ftplib.py was not updated when <br />
CVE-2021-4189 was fixed. While makepasv() was patched to replace <br />
server-supplied PASV host addresses with the actual peer address <br />
(getpeername()[0]), ftpcp() still calls parse227() directly and passes <br />
the raw attacker-controllable IP address and port to target.sendport(). This patch is related to CVE-2021-4189.
