It was noticed that a malicious process impersonating an Impala daemon in Apache Impala (incubating) 2.7.0 to 2.8.0 could cause Impala daemons to skip authentication checks when Kerberos is enabled (but TLS is not). If the malicious server responds with COMPLETE before the SASL handshake has completed, the client will consider the handshake as completed even though no exchange of credentials has happened.

Weakness

When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.

Affected Software

Name Vendor Start Version End Version
Impala Apache 2.7.0 (including) 2.7.0 (including)
Impala Apache 2.8.0 (including) 2.8.0 (including)
