CVE-2022-30260
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedEmerson DeltaV Distributed Control System (DCS) has insufficient verification of firmware integrity (an inadequate checksum approach, and no signature). This affects versions before 14.3 of DeltaV M-series, DeltaV S-series, DeltaV P-series, DeltaV SIS, and DeltaV CIOC/EIOC/WIOC IO cards.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceEmerson DeltaV DCS systems use an inadequate checksum method and lack cryptographic signature verification for firmware, allowing potentially malicious firmware to be loaded onto DeltaV M-series, S-series, P-series, SIS controllers and IO cards (CIOC/EIOC/WIOC) in versions before 14.3.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify DeltaV DCS deployment in your environmentReview asset inventories, network diagrams, or conduct field surveys to locate Emerson DeltaV Distributed Control System controllers and IO cards. Check for DeltaV software installations or DeltaV hardware in industrial control system racks.Affected if DeltaV DCS systems are present but their firmware versions cannot be confirmed as 14.3 or later
-
Check Sq and Sx Controller firmware versionsOpen DeltaV Explorer, navigate to the controller properties or diagnostics section, and record the firmware version displayed for each Sq and Sx controller. Alternatively, access controller diagnostics through the DeltaV operator interface or ProTech diagnostics.Affected if Controller firmware version is listed as less than 14.3
-
Check IO card terminal block firmware versionsIn DeltaV Explorer, expand the IO cards section and examine the firmware version properties for SE4002, SE4003, SE4017, and SE4019 IO modules. These may be listed under CIOC, EIOC, or WIOC configurations.Affected if Any SE4002, SE4003, SE4017, or SE4019 IO card firmware version is less than 14.3
-
Check fieldbus interface firmware versionsLocate the SE4019p0 Simplex H1 4 Port Plus Fieldbus I/O Interface in the DeltaV hardware hierarchy and verify its firmware version through the module properties in DeltaV Explorer or the system snapshot.Affected if SE4019p0 firmware version is less than 14.3
Your environment is affected if any DeltaV controller, IO card, or terminal block firmware is installed with a version number below 14.3, as these versions lack cryptographic signature verification for firmware integrity.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped14.3
Upgrade DeltaV firmware to version 14.3 or later which implements proper firmware integrity verification.
DeltaV firmware version 14.3 or later
- Verify the current firmware version of the DeltaV controller or I/O card by accessing the device diagnostics or control system management interface
- Confirm the current version is below 14.3 before proceeding with upgrade
- Obtain the firmware version 14.3 or later from Emerson's official support channels or authorized distributors
- Follow Emerson's standard firmware update procedure for DeltaV controllers: typically involves uploading the firmware file through the DeltaV Explorer or Control Studio management tool
- Ensure the control system is in a safe state before initiating firmware update - consider scheduling during a planned maintenance window
- Execute the firmware upgrade following Emerson's documented procedures for the specific controller or I/O card model
- After upgrade, verify the new firmware version is correctly installed and the device is operational
- Confirm that proper firmware signature verification is now enabled in the updated version
