Cloudera Technical Service Bulletin 2017-226 (TSB): Impala Statestore exposes plaintext data with SSL TLS enabled

Title: Impala Statestore exposes plaintext data with SSL TLS enabled 

During a security analysis, Cloudera found that despite TLS being enabled for “internal” Impala ports, the Statestore thrift port did not actually use TLS. This gap would allow an adversary with network access to eavesdrop and potentially modify the packets going to and coming from that port.

Products affected: Impala

Releases affected:
CDH 5.7 and lower
CDH 5.8.0, 5.8.1, 5.8.2, 5.8.3, 5.8.4
CDH 5.9.0, 5.9.1, 5.9.2
CDH 5.10.0, 5.10.1
CDH 5.11.0

Users affected: Deployments that use “internal” TLS (TLS between Impala daemons).

Date/time of detection: April 27, 2017

Detected by: Cloudera

Severity (Low/Medium/High): High

Impact: Data on the wire may be intercepted by a malicious server.

CVE: CVE-2017-5652

Immediate action required: Affected customers should upgrade to latest maintenance version with the fix.

Addressed in release/refresh/patch:
CDH 5.8.5, CDH 5.9.3, CDH 5.10.2, CDH 5.11.1, CDH 5.12.0
