Path Traversal in Apache Hive Disclosing File Contents

CVE-2018-1284

What is CVE-2018-1284?

In versions of Apache Hive ranging from 0.6.0 to 2.3.2, a vulnerability exists that permits a malicious user to exploit the XPath User Defined Functions (UDFs) to gain unauthorized access to files present on the server where HiveServer2 is running. If the configuration allows 'hive.server2.enable.doAs' to be set to false, attackers can manipulate XML inputs to reveal sensitive information from files owned by the HiveServer2 user, typically the 'hive' user. This vulnerability underscores the importance of enforcing strict configurations and access control measures in Hive deployments.
