Description Andrej Nemec 2019-01-31 10:20:39 UTC
HDFS exposes extended attribute key/value pairs during listXAttrs, verifying only path-level search access to the directory rather than path-level read permission to the referent. This affects features that store sensitive data in extended attributes, such as HDFS encryption secrets.

Comment 1 Andrej Nemec 2019-01-31 10:21:38 UTC
Mitigation:

If a file contains sensitive data in extended attributes, users and admins need to change the permission to prevent others from listing the directory which contains the file.
