OSIsoft reported this vulnerability to NCCIC.
OSIsoft recommends users upgrade to PI Vision 2017 R2 SP1 to address this
issue. This update can be obtained directly from OSIsoft.
Additionally, OSIsoft recommends the following defensive measures. All access
to the AF Server is protected by Windows authentication, so the modifications
to AF data items required by an attacker would have to be performed by a user
with write access to either the AF hierarchy or templates. Periodic review of
AF Server permissions to ensure only intended users are granted write access to
elements, element templates, and event frame templates is a good practice to
Similarly, which data items are available to PI Vision is controlled by the PI
Vision administrators through the administrative site. Only add data sources to
PI Vision that you can verify as legitimate with appropriate access control

NCCIC recommends users take defensive measures to minimize the risk of
exploitation of this vulnerability. Specifically, users should:
o Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet .
o Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
o When remote access is required, use secure methods, such as Virtual Private
Networks (VPNs), recognizing that VPNs may have vulnerabilities and should
be updated to the most current version available. Also recognize that VPN
is only as secure as the connected devices.
NCCIC reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.
NCCIC also provides a section for control systems security recommended
practices on the ICS-CERT web page. Several recommended practices are available
for reading and download, including Improving Industrial Control Systems
