Citrix ShareFile StorageZones Controller Multiple Security Updates

Security Bulletin | Medium | Created: 19 Sep 2018 | Modified: 19 Sep 2018

Applicable Products

  o ShareFile

Description of Problem

Two security issues have been identified within Citrix ShareFile StorageZones
Controller that, if exploited, could allow a compromised or malicious ShareFile
user to write arbitrary files as that Active Directory user to the local file
system, and also to discover the full local file system paths of shared files
to which the ShareFile user has access.

These issues affect all currently supported versions of Citrix ShareFile
StorageZones Controller before version 5.4.2.

The following issues have been addressed:

o CVE-2018-16968 (Medium): Citrix ShareFile StorageZones Controller before
5.4.2 allows Directory Traversal

o CVE-2018-16969 (Low): Citrix ShareFile StorageZones Controller before 5.4.2
has Information Exposure Through an Error Message

Mitigating Factors

These issues require a compromised or malicious ShareFile user in order to
exploit them.  To write files, the Active Directory user account must also have
local file system permissions to write files to the chosen location.  To read
the full path of a shared file, the ShareFile user account must also have
existing permission to the shared file.

What Customers Should Do

A new version of the Citrix ShareFile StorageZones Controller has been
released. Citrix recommends that affected customers review the risks that these
issues pose to their specific deployment and upgrade in a timely manner.

Citrix also recommends that the StorageZones Controller be configured such that
Active Directory user accounts only have permissions to read and write files
within the storage path root.

The StorageZones controller can be downloaded at the following location:
