CVE-2017-3162
HDFS clients interact with a servlet on the DataNode to browse the HDFS namespace.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.42%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
HDFS clients interact with a servlet on the DataNode to browse the HDFS namespace. The NameNode is provided as a query parameter that is not validated in Apache Hadoop before 2.7.0.
