Background
Apache Hadoop is an open-source framework used for distributed storage and processing of large datasets. It provides a scalable and reliable platform for big data analytics. The vulnerability in question affects versions 3.0.0-alpha1 to 3.0.0, 2.9.0, 2.8.0 to 2.8.3, and 2.5.0 to 2.7.5 of the Hadoop package. This vulnerability exposes extended attribute key/value pairs in Hadoop Distributed File System (HDFS) during the listXAttrs operation. The vulnerability only verifies path-level search access to the directory, rather than path-level read permission to the referent.
Vulnerability Detail
