CVE-2016-8365

OSIsoft PI System software (Applications using PI Asset Framework (AF) Client versions prior to PI AF Client 2016, Version 2.8.0; Applications using PI Software Development Kit (SDK) versions prior to PI SDK 2016, Version 1.4.6; PI Buffer Subsystem, versions prior to and including, Version 4.4; and PI Data Archive versions prior to PI Data Archive 2015, Version 3.4.395.64) operates between endpoints without a complete model of endpoint features potentially causing the product to perform actions based on this incomplete model, which could result in a denial of service. OSIsoft reports that in order to exploit the vulnerability an attacker would need to be locally connected to a server. A CVSS v3 base score of 7.1 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H)

Base score Version Severity Vector Exploitability Impact Score source
5.5 3.0 MEDIUM
CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.

Exploitation conditions are straightforward and predictable.
Authentication (AU:N)
No authentication is required.
Confidentiality impact (C:N)
No confidentiality impact.
Integrity impact (I:N)
No integrity impact.
