02 Description

Deserialization of Untrusted Data in AVEVA PI Web API

03 Exploitation and scoring

Exploitation
Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
SSVC decision
  • ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
  • AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
  • Technical ImpactpartialSuccessful exploitation gives limited control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.
EPSS probability
0.41% probability of exploitation activity in the next 30 days.
EPSS percentile
Equal to or higher than the score of 35.6% of scored records. A rank, not a probability.
NVD base score
8.4 (CVSS v4.0), scored by the NVD independently of the CNA.

07 Remediation

AVEVA recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation. Customers using affected products should apply security updates as soon as possible: From OSI Soft Customer Portal https://my.osisoft.com/ , search for "PI Web API" and select version "2023 SP1" or later. (Alternative) PI Web API 2021 SP3 can be fixed by upgrading PI AF Client to one of the versions specified in AVEVA Security Bulletin AVEVA-2024-004 / ICSA-24-163-03 AVEVA further recommends users follow general defensive measures: * Set "DisableWrites" configuration setting to true, if this instance of PI Web API is used only for reading data or GET requests. * Uninstall Core Endpoints feature if this instance of PI Web API is used only for data collection from AVEVA Adapters. Keep OMF feature installed. * Limit AF Servers' Administrators, so that most of the PI Web API user accounts don't have the permission to change the backend AF servers.
