Summary
wget vulnerability
Details

It was discovered that Wget did not properly validate the IP address provided in an FTP PASV response when operating in FTP passive mode. A remote attacker controlling a malicious FTP server, or an HTTP server that redirects to an FTP URL, could possibly use this issue to redirect Wget's data connection to an arbitrary address and perform server-side request forgery, potentially accessing localhost services or internal network resources.
