Apache Impala 2.8.0 Plain-Text Information Disclosure

Apache Impala 2.8.0 Plain-Text Information Disclosure
Posted Jul 10, 2017
Authored by Cloudera

Apache Impala versions 2.7.0 through 2.8.0 suffers from an information disclosure vulnerability. During a routine security analysis, it was found that one of the ports sent data in plaintext even when the cluster was configured to use TLS. The port in question was used by the StatestoreSubscriber class which did not use the appropriate secure Thrift transport when TLS was turned on. It was therefore possible for an adversary, with access to the network, to eavesdrop on the packets going to and coming from that port and view the data in plaintext.
