CVE-2020-12014
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 · uneditedAdvantech WebAccess Node, Version 8.4.4 and prior, Version 9.0.0. Input is not properly sanitized and may allow an attacker to inject SQL commands.
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 confidenceSQL injection vulnerability in Advantech WebAccess Node versions 8.4.4 and prior, and version 9.0.0 allows attackers to inject malicious SQL commands due to improper input sanitization. This could enable unauthorized database access, data exfiltration, or manipulation.

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 Advantech WebAccess Node installationLocate the WebAccess Node installation directory or check installed programs list for 'Advantech WebAccess Node'Affected if The product is not installed on the system, then not affected
-
Determine installed versionCheck the installed version of Advantech WebAccess Node in the application or its installer. Common locations include the application About dialog, installer logs, or version information in the installation directoryAffected if The installed version is 8.4.4 or lower, OR the installed version is exactly 9.0.0
-
Verify database connectivity is in useConfirm that the WebAccess Node installation is configured to use a backend database, as the SQL injection vulnerability requires database operations to be exploitableAffected if The application uses a backend database (SQL injection targets database query handling)
-
Check web interface exposureDetermine if the WebAccess Node web interface is accessible from network endpoints, as the SQL injection is exploited through web input fieldsAffected if The web interface is exposed to network users or untrusted inputs
The system is affected if Advantech WebAccess Node is installed with version 8.4.4 or lower, or exactly version 9.0.0, and the web interface with database connectivity is in use.
