CVE-2021-27468
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 · uneditedThe AosService.rem service in Rockwell Automation FactoryTalk AssetCentre v10.00 and earlier exposes functions lacking proper authentication. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary SQL statements.
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.

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 FactoryTalk AssetCentre versionLocate the installed version of FactoryTalk AssetCentre in the system (check program files, registry, or application documentation for version information)Affected if The installed version is 10.00 or earlier
-
Confirm AosService.rem component existsVerify that the AosService.rem service component is present in the FactoryTalk AssetCentre installationAffected if The AosService.rem service is installed and present on the system
-
Check if the remoting service is enabled or runningDetermine whether the AosService.rem service is in a running or enabled state, or if the remoting endpoint is listening on its configured portAffected if The AosService.rem service is running, enabled, or listening on a network port
-
Assess network exposure of the serviceReview network configuration, firewall rules, or listening ports to determine if the AosService.rem endpoint is accessible from external network segments or untrusted hostsAffected if The AosService.rem service is exposed to untrusted network access (e.g., accessible from outside the local network or from untrusted systems)
You are affected if FactoryTalk AssetCentre version 10.00 or earlier is installed with the AosService.rem component exposed and accessible on the network.

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 dataApply vendor patches if available; otherwise restrict network access to the AosService.rem through firewall rules or network segmentation to prevent unauthenticated remote exploitation.
