CWEhttps://cwe.mitre.org/data/definitions/345.html

The ftp client in GNU Inetutils before 2.2 does not validate addresses returned by PASV/LSPV responses to make sure they match the server address. This is similar to CVE-2020-8284 for curl.

Weakness

The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
