CVE-2020-7010

Credential compromise via deployment-time-seeded password generation

Published Jun 3, 2020 · Updated Nov 18, 2024

Weak password generation in Elastic Cloud on Kubernetes 1.0.0 and 1.0.1 allows attackers to brute-force generated Elasticsearch credentials. The default credential generator seeds a weak pseudorandom process with deployment-time information, sharply reducing the password search space. Exploitation requires knowledge of the cluster deployment time and applies only while the original auto-generated credentials remain in use.
