CVE-2024-6207
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 · uneditedCVE 2021-22681 https://www.rockwellautomation.com/en-us/trust-center/security-advisories/advisory.PN1550.html and send a specially crafted CIP message to the device. If exploited, a threat actor could help prevent access to the legitimate user and end connections to connected devices including the workstation. To recover the controllers, a download is required which ends any process that the controller is running.
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 · moderate confidenceThis is a denial of service vulnerability in Rockwell Automation controllers exploitable via specially crafted CIP (Common Industrial Protocol) messages. Successful exploitation prevents legitimate user access and disconnects connected devices including workstations. Recovery requires a controller download, which terminates all running processes.

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 the controller modelDetermine the exact Rockwell Automation controller model in your environment (e.g., Controllogix 5580, Compactlogix 5380, Guardlogix 5580, Compactlogix 5480, or Factorytalk Logix Echo). Check controller labels, RSLinx Classic or FactoryTalk Linx device browser, or the controller's web-based interface.Affected if The controller model is one of the affected products listed in the CVE advisory.
-
Retrieve the installed firmware versionAccess the controller firmware version via RSLinx Classic (right-click controller > Device Properties), FactoryTalk Linx, the controller's web interface (if available), or via Studio 5000 Logix Designer (go to Controller Properties > General).Affected if The firmware version falls within any of these ranges: >= 28.011 and < 33.017; >= 34.011 and < 34.014; >= 35.011 and < 35.013 (specific ranges vary by controller model).
-
Verify CIP communication is enabledCheck if the controller has CIP (Common Industrial Protocol) messaging enabled and is exposed to the network. In RSLinx Classic, verify the CIP driver (e.g., Ethernet/IP driver) is running and the controller is browsable. In FactoryTalk Linx, check the network topology for active CIP connections.Affected if CIP is enabled and the controller is network-accessible, making it reachable for specially crafted CIP messages.
-
Assess network exposureReview network architecture to determine if the controller is directly accessible from less-trusted networks. Check firewall rules, VLAN configurations, and network segmentation around the industrial control system. Identify if the controller has an IP address on a network segment that could receive untrusted CIP traffic.Affected if The controller is accessible from network segments beyond the isolated industrial control environment, increasing exploitability.
You are affected if your controller is one of the affected models listed, runs a firmware version within the vulnerable ranges, and has CIP communication enabled and network-accessible.

Implement network segmentation to isolate industrial control systems, apply CIP message filtering at network boundaries, and review Rockwell Automation advisory PN1550 for specific device patches and hardening guidance.
Firmware version 33.017 or later (or 34.014 or later, or 35.013 or later depending on the version track for your specific controller)
- 1. Identify the exact Controllogix/Guardlogix/Compactlogix controller model and current firmware version installed on the device
- 2. Navigate to the Rockwell Automation Product Compatibility and Download Center (PCDC) at https://compatibility.rockwellautomation.com/
- 3. Search for the specific controller model to find available firmware updates
- 4. Download firmware version 33.017 or later (or 34.014 or later, or 35.013 or later) that is compatible with your hardware revision
- 5. Review release notes for any special installation instructions or prerequisites
- 6. Backup controller project and configuration data before performing firmware update
- 7. Upload the current project from the controller to preserve logic and tags
- 8. Update firmware using RSLinx Classic or FactoryTalk Linx with ControlFLASH or ControlFLASH Plus utility
