Status: ModifiedMedium (5.3)—

AVEVA PI Server versions 2023 and 2018 SP3 P05 and prior contain a vulnerability that could allow an unauthenticated user to cause the PI Message Subsystem of a PI Server to consume available memory resulting in throttled processing of new PI Data Archive events and a partial denial-of-service condition.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
