AI-suggested

To mitigate CVE-2025-62877, European organizations should immediately avoid using the interactive installer for creating new clusters or adding hosts in SUSE Harvester versions 1.5.0 and 1.6.0. Instead, they should deploy clusters using the PXE boot mechanism combined with the Harvester configuration setup, which is not affected by this vulnerability. Organizations should monitor SUSE’s official channels for patches or updated versions that address this issue and plan prompt upgrades once available. Additionally, network-level controls such as restricting SSH access to trusted management networks, implementing strict firewall rules, and employing intrusion detection systems can reduce exposure. It is also advisable to audit existing deployments for the presence of default SSH credentials and enforce immediate password changes or key-based authentication. Regular vulnerability scanning and penetration testing focused on SSH access can help detect exploitation attempts. Finally, organizations should update incident response plans to include this vulnerability and educate administrators on secure deployment practices for SUSE Harvester.

Description

Projects using the SUSE Virtualization (Harvester) environment may expose the OS default ssh login password  if they are using the 1.5.x or 1.6.x interactive installer to either create a new cluster or add new hosts to an existing cluster. The environment is not affected if the PXE boot mechanism is utilized along with the Harvester configuration setup.
