CVE-2021-3426: Remove the ``getfile`` feature of the :mod:`pydoc` module
|
||||
which could be abused to read arbitrary files on the disk (directory
|
||||
traversal vulnerability). Moreover, even source code of Python modules can
|
||||
contain sensitive data like passwords. Vulnerability reported by David
|
||||
Schwörer.

:mod:`ftplib` no longer trusts the IP address value returned from the server
|
||||
in response to the PASV command by default. This prevents a malicious FTP
|
||||
server from using the response to probe IPv4 address and port combinations
|
||||
on the client network.
|
||||
|
||||
Code that requires the former vulnerable behavior may set a
|
||||
``trust_server_pasv_ipv4_address`` attribute on their :class:`ftplib.FTP`
|
||||
instances to ``True`` to re-enable it.

:mod:`ftplib` no longer trusts the IP address value returned from the server
|
||||
in response to the PASV command by default. This prevents a malicious FTP
|
||||
server from using the response to probe IPv4 address and port combinations
|
||||
on the client network.
|

|

Code that requires the former vulnerable behavior may set a
|
||||
``trust_server_pasv_ipv4_address`` attribute on their
|
||||
:class:`ftplib.FTP` instances to ``True`` to re-enable it.
