wget prior to 1.16 allows for a web server to write arbitrary files on the client side

Here's a concern for most of us. Be aware that the popular program wget, in versions prior to 1.16, allows for a FTP server to write arbitrary files on the client side. Wget is commonly used in shell scripts to get files or web pages from servers for further processing locally. Wget has many other uses as well, and is an important part of much command line sorcery.

A Metasploit module is available for testing:

Note that it applies only to using wget with both an FTP connexion and recursive flags, which significantly reduces it's potential.

Not to say that it is not a serious one, it is, but it's not as bad as wget on a http url for a single file (which is something I do daily). Now, that would be really messy.
