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.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
