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 CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability exists in EcoStruxure Operator Terminal Expert 3.1 Service Pack 1 and prior (formerly known as Vijeo XD) which could cause malicious code execution when opening the project file.
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 SQL injection vulnerability in EcoStruxure Operator Terminal Expert 3.1 SP1 and prior allows malicious code execution when opening a specially crafted project file. The application fails to properly sanitize special elements in the project file before using them in SQL commands, enabling arbitrary code execution.

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.
-
Verify EcoStruxure Operator Terminal Expert installationCheck if the application is installed on the system by looking in Add or Remove Programs (Windows) or searching for the executable (typically located in C:\Program Files\Schneider Electric\EcoStruxure Operator Terminal Expert or similar)Affected if The application is present on the system
-
Determine installed versionOpen the application and navigate to Help > About, or check the version in Add/Remove Programs. The version may also be visible in the executable properties by right-clicking the main executable and selecting Properties > DetailsAffected if Unable to determine version or version is unknown
-
Compare version against affected rangesCheck if the installed version matches <= 3.0 or equals 3.1. Versions prior to 3.1 Service Pack 2 are affectedAffected if Version is 3.1 or any version <= 3.0
-
Confirm project file handling is in useThe vulnerability triggers when opening specially crafted project files (.estux or similar project formats used by this application). This is the primary function of the softwareAffected if The application is used to open or manage project files from any source
The environment is affected if EcoStruxure Operator Terminal Expert version 3.1 or any version <= 3.0 is installed and used to open project files, as the SQL injection flaw exists in the project file parsing logic of these versions.
