Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.10 host has packages installed that are affected by a vulnerability as referenced in the USN-6589-1 advisory.

 Fabian Baeumer, Marcus Brinkmann and Joerg Schwenk discovered that the SSH protocol used in FileZilla is prone to a prefix truncation attack, known as the Terrapin attack. A remote attacker could use this issue to downgrade or disable some security features and obtain sensitive information.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
