CVE-2021-3620
Description
A flaw was found in Ansible Engine's ansible-connection module, where sensitive information such as the Ansible user credentials is disclosed by default in the traceback error message. The highest threat from this vulnerability is to confidentiality.
Statement
Red Hat Gluster Storage 3 no longer maintains its own version of Ansible. The prerequisite is to enable the Ansible repository in order to consume the latest version of Ansible, which has many bug and security fixes.
Red Hat Ceph Storage 2 only provides fixes for bugs on an as-requested basis by a customer, and will not be fixed after discussion with engineering about the viability of a fix. Red Hat Ceph Storage 3 does not directly ship ansible, and thus is closed as won't fix.
Red Hat Virtualization ships an affected version of ansible, however, the usage of ansible on the redhat-virtualization-host is only supported for self-hosted-engine installation and disaster recovery, where it is run locally. As such Impact is rated Moderate.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Often this will either reveal sensitive information which may be used to launch another, more focused attack or disclose private information stored in the server. For example, an attempt to exploit a path traversal weakness (CWE-22) might yield the full pathname of the installed application. In turn, this could be used to select the proper number of ".." sequences to navigate to the targeted file. An attack using SQL injection (CWE-89) might not initially succeed, but an error message could reveal the malformed query, which would expose query logic and possibly even passwords or other sensitive information used within the query.
