CVE-2022-29966

Summary

The Emerson Ovation system exposes several protocols without authentication, allowing unauthenticated remote attackers to modify controller configurations or trigger denial-of-service conditions.

Exploitability

Exploitation is trivial for an attacker with network access to the affected systems, as no authentication is required.

Blast radius

Successful exploitation could lead to full compromise of operational technology (OT) systems, including unauthorized control changes or plant shutdowns.

Detection

Look for unauthenticated protocol traffic to Ovation controller endpoints (e.g., Modbus/TCP, DNP3 over TCP) from unexpected source IPs or atypical times; no specific log fields are documented in the CVE description.

Prioritized remediation

Apply Emerson security advisory SA-71324 Rev. 1.0, which recommends enabling authentication on all exposed protocols and restricting network access via firewall rules; no fixed software version is specified in the CVE description.
