How to fix?

There is no fixed version for RHEL:7 etcd.

NVD Description

Note: Versions mentioned in the description apply only to the upstream etcd package and not the etcd package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

In etcd before versions 3.3.23 and 3.4.10, certain directory paths are created (etcd data directory and the directory path when provided to automatically generate self-signed certificates for TLS connections with clients) with restricted access permissions (700) by using the os.MkdirAll. This function does not perform any permission checks when a given directory path exists already. A possible workaround is to ensure the directories have the desired permission (700).
