CVE-2020-1731Network attack vector

Administrator access via deterministic password generation

Published Mar 2, 2020 · Updated Aug 4, 2024

Predictable credentials in Red Hat build of Keycloak's community Operator before 8.0.2 allow remote attackers to gain administrator access. KeycloakAdminSecret uses the unseeded math/rand generator to populate the credential Secret, causing fresh deployments to repeat its deterministic sequence. Exposure requires the community Operator and network access to the Keycloak administration interface; successful login grants administrative control.
