Vendor: OSIsoft

Equipment: PI Integrator

Vulnerabilities: Cross-Site Scripting, Improper Authorization


The following versions of PI Integrator, a data management platform,
are affected:

PI Integrator for SAP HANA 2016,
PI Integrator for Business Analytics 2016 - Data Warehouse (All Editions),
PI Integrator for Business Analytics 2016 - Business Intelligence (All Editions),
PI Integrator for Business Analytics and SAP HANA SQL Utility 2016, and

Successful exploitation of these vulnerabilities could allow an unauthorized
attacker to gain privileged access to the system. An attacker may also be
able to store a malicious script in the application database.


OSIsoft recommends that users update their software at the earliest
opportunity. Users and administrators are encouraged to upgrade to PI
Integrator for Business Analytics 2016 R2 or later, PI Integrator for
Microsoft Azure 2016 R2 SP1 or later, or PI Integrator for SAP HANA 2017
or later for the corresponding edition.

NCCIC/ICS-CERT recommends that users take defensive measures to minimize the
risk of exploitation of these vulnerabilities. Specifically, users should:

Minimize network exposure for all control system devices and/or systems,
and ensure that they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls, and
isolate them from the business network.
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.

ICS-CERT reminds organizations to perform proper impact analysis and risk
assessment prior to deploying defensive measures.

ICS-CERT 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 Cybersecurity with Defense-in-Depth Strategies.

Additional mitigation guidance and recommended practices are
publicly available in the ICS-CERT Technical Information Paper,
ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation
Strategies, that is available for download from the ICS-CERT web site.

Organizations observing any suspected malicious activity should follow their
established internal procedures and report their findings to ICS-CERT for
tracking and correlation against other incidents.

No known public exploits specifically target these vulnerabilities.



An attacker may be able to upload a malicious script that attempts to
redirect users to a malicious web site.
