CVE-2022-30267

Description

A flaw was found in Ovation. The software fails to authenticate firmware signatures and relies on an insecure checksum to verify integrity. A remote, unauthenticated attacker could exploit this issue by delivering a crafted firmware image to the system. Successful exploitation may allow an attacker to achieve arbitrary code execution or cause a Denial of Service (DoS) condition.

Statement

This vulnerability is rated as Important because remote, unauthenticated attackers can leverage insecure integrity verification to deploy compromised firmware and potentially achieve high-impact availability disruption or code execution. However, Emerson Ovation is proprietary third-party industrial control system software that is neither developed nor distributed by Red Hat. As a result, no Red Hat product offerings are affected by this flaw.

Mitigation

--- CME Mitigation Guidance (2026-11-06) ---
Disclaimer: The following mitigation solutions are provided as a courtesy, pending the application of an official patch. This content was generated utilizing AI tools in conjunction with data from https://cmetaxonomy.org. Customers are advised to independently evaluate and test these temporary mitigations within their own infrastructure.

The highest-value action is to enforce cryptographic firmware signature authentication and block unauthenticated firmware uploads to controller interfaces: upgrade to Ovation 3.8.0 Feature Pack 3, which authenticates cryptographic firmware signatures before flashing instead of relying solely on insecure checksums for integrity verification, closing all 2 injection vectors (malicious firmware upload, unverified firmware image injection). Until patched, this is a concern on Emerson Ovation controller and system network interfaces, so Isolate control networks behind firewalls, restrict remote access through VPNs, and ensure controller interfaces are inaccessible from untrusted networks. These controls limit blast radius and contain exploitation, but they do not fix the underlying missing firmware signature authentication defect — apply the upstream patch to fully remediate.

Understanding the Weakness (CWE)

Integrity,Availability,Confidentiality,Other

Technical Impact: Execute Unauthorized Code or Commands; Alter Execution Logic; Other

An attacker can execute malicious code by compromising the host server, performing DNS spoofing, or modifying the code in transit. Executing untrusted code could compromise the control flow of the program. The untrusted code could execute attacker-controlled commands, read or modify sensitive resources, or prevent the software from functioning correctly for legitimate users.
