The Dell Isilon OneFS versions 8.2.2 and earlier and Dell EMC PowerScale OneFS version 9.0.0 default configuration for Network File System (NFS) allows access to an 'admin' home directory. An attacker may leverage a spoofed Unique Identifier (UID) over NFS to rewrite sensitive files to gain administrative access to the system.
