CVE-2021-27472
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 · uneditedA vulnerability exists in the RunSearch function of SearchService service in Rockwell Automation FactoryTalk AssetCentre v10.00 and earlier, which may allow for the execution of remote unauthenticated 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.
dbcve analysis · high confidenceA critical SQL injection vulnerability exists in the RunSearch function of the SearchService in Rockwell Automation FactoryTalk AssetCentre v10.00 and earlier. The flaw allows remote unauthenticated attackers to execute arbitrary SQL statements, likely due to improper input sanitization in the search query handling.

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 AssetCentre installationCheck for the presence of FactoryTalk AssetCentre software on the system. Look for the product in Windows Add/Remove Programs, or check for the installation directory under Program Files/Rockwell Software/FactoryTalk AssetCentre.Affected if FactoryTalk AssetCentre is installed on the system
-
Check installed version numberOpen the Windows Control Panel and view the installed version of FactoryTalk AssetCentre in Programs and Features, or check the version information in the software's About/Help section.Affected if The installed version is 10.00 or earlier (any version up to and including 10.00)
-
Identify if SearchService is running and exposedCheck Windows Services for the SearchService related to FactoryTalk AssetCentre. Use netstat or a port scanner to determine if the SearchService port is listening on network interfaces accessible from outside.Affected if SearchService is running and bound to a network-accessible IP address (not localhost only)
-
Verify SearchService is accessible without authenticationAttempt to access the SearchService endpoint from a remote system or check configuration files for the service to determine if authentication is required for the RunSearch function.Affected if The RunSearch function does not require authentication or lacks proper input validation controls
The environment is affected if FactoryTalk AssetCentre version 10.00 or earlier is installed and the SearchService is network-accessible without proper authentication controls on the RunSearch function.

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 the vendor patch when available; in the interim, restrict network access to the SearchService port and monitor for suspicious SQL patterns in search queries.
