CVE-2021-3585

Local RHSM password disclosure via retry logging

Published Aug 26, 2022 · Updated Aug 3, 2024

Cleartext credential exposure in OpenStack TripleO Heat Templates before 8.4.1 allows local users to read RHSM passwords from deployment logs. The legacy rhel-registration workflow leaves its subscription-manager password unredacted when a failed task writes retry data and log output. Exposure requires an OSP13 deployment using subscription-manager and grants access to the recorded RHSM credential without altering or interrupting the deployment.
