The XML parser in EMC Atmos before 2.2.3.426 and 2.3.x before 2.3.1.0 allows remote authenticated users to read arbitrary files or cause a denial of service (CPU and memory consumption) via an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.

EMC Atmos before 2.1.4 has a blank password for the PostgreSQL account, which allows remote attackers to obtain sensitive administrative information via a database-server connection.
