What is CVE-2020-5353?

The default configuration of Network File System (NFS) in Dell Isilon OneFS and Dell EMC PowerScale OneFS versions exposes the 'admin' home directory, which could be accessed by attackers. By spoofing a Unique Identifier (UID) over NFS, an unauthorized individual may write sensitive files, potentially gaining administrative privileges and compromising the integrity of the system. This highlights critical considerations for file system security and proper configuration management.
