CVSS v4.8
**ATTENTION:**Low skill level to exploit
**Vendor:**OSIsoft
**Equipment:**PI Vision
**Vulnerability:**Cross-site Scripting
Successful exploitation of this vulnerability could allow an attacker to read and modify the contents of the PI Vision web page and data related to the PI Vision application in the victimβs browser.
The following versions of PI Vision, a process visualization tool are affected:
3.2.1 IMPROPER NEUTRALIZATION OF INPUT DURING WEB PAGE GENERATION (βCROSS-SITE SCRIPTINGβ) CWE-79
The application contains a cross-site scripting vulnerability where displays that reference AF elements and attributes containing JavaScript are affected. This vulnerability requires the ability of authorized AF users to store JavaScript in AF elements and attributes.
CVE-2018-19006 has been assigned to this vulnerability. A CVSS v3 base score of 4.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N).
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 reduce exposure.
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 configured.
