An unclaimed Amazon S3 bucket, 'codeconf', is referenced in an audio file link within the .rst documentation file. This bucket has been claimed by an external party. The use of this unclaimed S3 bucket could lead to data integrity issues, data leakage, availability problems, loss of trustworthiness, and potential further attacks if the bucket is used to host malicious content or as a pivot point for further attacks.

Requests is a HTTP library. Prior to 2.32.0, when making requests through a Requests `Session`, if the first request is made with `verify=False` to disable cert verification, all subsequent requests to the same host will continue to ignore cert verification regardless of changes to the value of `verify`. This behavior will continue for the lifecycle of the connection in the connection pool. This vulnerability is fixed in 2.32.0.

A use-after-free issue could be triggered remotely in the SFTP component of PSFTPd 10.0.4 Build 729. This issue could be triggered prior to authentication. The PSFTPd server did not automatically restart, which enabled attackers to perform a very effective DoS attack against this service. By sending a crafted SSH identification / version string to the server, a NULL pointer dereference could be caused, apparently because of a race condition in the window message handling, performing the cleanup for invalid connections. This incorrect cleanup code has a use-after-free.

The PSFTPd 10.0.4 Build 729 server does not prevent FTP bounce scans by default. These can be performed using "nmap -b" and allow performing scans via the FTP server.

The PSFTPd 10.0.4 Build 729 server does not properly escape data before writing it into a Comma Separated Values (CSV) file. This can be used by attackers to hide data in the Graphical User Interface (GUI) view and create arbitrary entries to a certain extent. Special characters such as '"' and ',' and '\r' are not escaped and can be used to add new entries to the log.

The PSFTPd 10.0.4 Build 729 server stores its configuration inside PSFTPd.dat. This file is a Microsoft Access Database and can be extracted. The application sets the encrypt flag with the password "ITsILLEGAL"; however, this password is not required to extract the data. Cleartext is used for a user password.

The Appsflyer library for Android does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate.

inc.login.php in PHPsFTPd 0.2 through 0.4 allows remote attackers to obtain the administrator's username and password by setting the do_login parameter and performing an edit action using user.php, which causes the login check to be bypassed and leaks the password in the response.
