Information disclosure in Linuxfoundation Baremetal Operator
CVE-2023-30841
Baremetal Operator (BMO) is a bare metal host provisioning integration for Kubernetes. Prior to version 0.3.0, ironic and ironic-inspector deployed within Baremetal Operator using the included `deploy.sh` store their `.htpasswd` files as ConfigMaps instead of Secrets. This causes the plain-text username and hashed password to be readable by anyone having a cluster-wide read-access to the management cluster, or access to the management cluster's Etcd storage. This issue is patched in baremetal-operator PR#1241, and is included in BMO release 0.3.0 onwards. As a workaround, users may modify the kustomizations and redeploy the BMO, or recreate the required ConfigMaps as Secrets per instructions in baremetal-operator PR#1241.
