CVE-2020-15113
MEDIUM5.7EPSS 0.02%Improper Preservation of Permissions in etcd
Published: 1/30/2024Modified: 4/28/2026
Description
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).
