CVE-2022-38744
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 · uneditedAn unauthenticated attacker with network access to a victim's Rockwell Automation FactoryTalk Alarm and Events service could open a connection, causing the service to fault and become unavailable. The affected port could be used as a server ping port and uses messages structured with XML.
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 FactoryTalk Alarm and Events service. An unauthenticated attacker with network access can open a connection to the affected service port (which functions as a server ping port using XML-structured messages), causing the service to fault and become unavailable.

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.
-
Confirm FactoryTalk Alarm and Events installationOpen Windows Services console (services.msc) and look for a service named 'FactoryTalk Alarm and Events' or check Programs and Features for Rockwell Automation FactoryTalk Alarm and Events entryAffected if The product is installed on the system
-
Identify the service executableIn Services console, right-click the FactoryTalk Alarm and Events service, select Properties, and note the path to the executable (.exe) - typically under C:\Program Files\Rockwell Software\ or similar Rockwell installation directoryAffected if A FactoryTalk Alarm and Events service executable is found at a Rockwell Software path
-
Verify the service is listening on a portOpen Command Prompt and run 'netstat -anob | findstr /i "FactoryTalk"' or use Process Explorer to identify which port the service is bound to; the affected port functions as a server ping port using XML-structured messagesAffected if The service is actively listening on a TCP port (typically port 4567 or similar, but the specific port varies by configuration)
-
Assess network exposure of the service portRun 'netstat -an' and identify the IP binding for the FactoryTalk service port (0.0.0.0 means exposed to all interfaces); verify firewall rules allow inbound connections to this port from untrusted networks using 'netsh advfirewall firewall show rule name=all'Affected if The service port is bound to 0.0.0.0 or an accessible IP and firewall rules permit inbound connections from untrusted sources
If FactoryTalk Alarm and Events is installed and its service port is network-accessible to untrusted hosts, the environment is affected by this CVE.

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.
From vendor dataRestrict network access to the FactoryTalk Alarm and Events service by implementing firewall rules and network segmentation to limit exposure to only trusted IP addresses; monitor for service availability issues.
