AVEVA PI Data Archive Vulnerability Exposes Systems to DoS Attacks (ICSA-26-041-03)
CISA warns of a critical denial-of-service vulnerability in AVEVA PI Data Archive versions ≤2018_SP3. Immediate patching recommended for OT environments.
AVEVA PI Data Archive Vulnerability Could Enable DoS Attacks
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued an advisory (ICSA-26-041-03) warning of a vulnerability in AVEVA PI Data Archive that could lead to a denial-of-service (DoS) condition in operational technology (OT) environments.
Technical Details
The vulnerability affects the following versions of AVEVA PI Data Archive:
- PI Data Archive PI Server ≤2018_SP3
While CISA has not disclosed the specific CVE ID or technical root cause in the initial advisory, successful exploitation could disrupt critical data collection and monitoring functions in industrial control systems (ICS).
Impact Analysis
AVEVA PI Data Archive is widely used in industrial sectors, including energy, manufacturing, and water treatment, to collect, store, and analyze real-time operational data. A DoS condition could:
- Disrupt process visibility for operators
- Delay critical decision-making in time-sensitive environments
- Increase operational risk if monitoring systems fail
Given the advisory’s classification under ICS security, organizations using affected versions should prioritize remediation to prevent potential exploitation.
Recommendations
CISA urges affected organizations to:
- Apply vendor-provided patches as soon as they become available.
- Monitor network traffic for anomalous activity targeting PI Data Archive systems.
- Implement compensating controls, such as network segmentation, to limit exposure.
- Review CISA’s CSAF document for additional technical guidance.
