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.
AnalysisAI
SUSE Harvester virtualization environment (1.5.x, 1.6.x) exposes the OS default SSH login password when using the interactive installer. This affects all hosts provisioned through the interactive method, potentially compromising entire virtualization clusters.
Technical ContextAI
The interactive installer sets a default SSH password (CWE-1188) that is not forced to be changed after installation. All hosts provisioned this way share the same credential, creating a single point of failure for the entire Harvester cluster.
Affected ProductsAI
SUSE Harvester 1.5.x, 1.6.x (interactive installer method only; PXE boot not affected)
RemediationAI
Change the SSH password on all Harvester hosts immediately. Use PXE boot with Harvester configuration for future provisioning.
