Authentication bypass in Apache Druid LDAP authenticator (anonymous bind)
Apache Druid contains an authentication bypass in the druid-basic-security extension’s LDAP authentication flow. When Druid is configured to use an LDAP authenticator and the backing LDAP server permits anonymous binds, Druid improperly validates the LDAP bind result such that an attacker can supply an existing username with an empty password and be treated as successfully authenticated. The issue is effectively caused by accepting an “anonymous bind success” response as proof of authentication for the provided username, enabling login without valid credentials. Affected versions are Apache Druid 0.17.0 through all 35.x releases (i.e., all versions prior to 36.0.0).

An authentication bypass in Apache Druid’s druid-basic-security extension when using an LDAP authenticator. If the LDAP server permits anonymous binds, Druid can incorrectly treat an anonymous bind success as successful authentication for a supplied username with an empty password, enabling remote unauthenticated access with the impersonated user’s privileges.
