What is CVE-2017-3162?

The vulnerability in Apache Hadoop's DataNode web UI arises from a lack of validation for the NameNode query parameter. HDFS clients interacting with the servlet are exposed to potential security risks, as the arbitrary input can compromise the namespace browsing functionality. This flaw enables unauthorized users to obtain sensitive information about the Hadoop distributed file system, making it essential for users to update to the patched versions or implement protective measures.

Affected Version(s)

Apache Hadoop 2.6.x and earlier
