Description
A flaw was found in Wget. When operating in FTP passive mode, Wget fails to validate the IP address provided in an FTP PASV response. A malicious FTP server, or an HTTP server that redirects to an FTP URL, can exploit this vulnerability to redirect Wget's data connection to an arbitrary IP address and port. This allows an attacker to forge server-side requests (SSRF) from the machine running Wget, potentially leading to unauthorized access to localhost services or internal network resources.
