CVE-2025-23390 | BDVDB-2026-389652 Detail

SUSEfleet

Description#

A vulnerability has been identified within Fleet where, by default, Fleet will automatically trust a remote server’s certificate when connecting through SSH if the certificate isn’t set in the `known_hosts` file. This could allow the execution of a man-in-the-middle (MitM) attack against Fleet. In case the server that is being connected to has a trusted entry in the known_hosts file, then Fleet will correctly check the authenticity of the presented certificate.

Impact#

Per CVSS v3.1: confidentiality impact low, integrity impact low, availability impact low. Attack vector: network.

Weaknesses#
