CVE-2020-7547
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-284: Improper Access Control vulnerability exists in EcoStruxureª and SmartStruxureª Power Monitoring and SCADA Software (see security notification for version information) that could allow a user the ability to perform actions via the web interface at a higher privilege level.
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 confidenceImproper Access Control vulnerability in EcoStruxure and SmartStruxure Power Monitoring and SCADA Software web interface allows authenticated users to perform actions at a higher privilege level than assigned, enabling privilege escalation.

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 the installed Schneider Electric productCheck the installed software on the system for one of: EcoStruxure Energy Expert, EcoStruxure Power Monitoring Expert, Power Manager, PowerSCADA Expert, or PowerSCADA Operation. Look in Programs and Features (Windows) or use system inventory tools.Affected if Any of the listed products are installed
-
Determine the installed versionOpen the product's about or version information panel, check the installation directory for a version file, or run the application's version command. Compare against: EcoStruxure Energy Expert = 2.0; Power Monitoring Expert = 7.0, 8.0, or 9.0; Power Manager = 1.1, 1.2, or 1.3; PowerSCADA Expert = 8.0; PowerSCADA Operation = 9.0Affected if The installed version exactly matches one of the affected versions listed
-
Verify the web interface is enabledCheck if the product's web interface service or web server component is running and accessible. Look for web service processes (e.g., IIS, Apache, or built-in web server) and verify the application port is listening.Affected if The web interface service is running and accessible on the network
-
Confirm user authentication is configuredCheck if local or domain user accounts are configured for the application. Review user management settings, authentication configuration, or user databases to determine if login is possible.Affected if User accounts are configured and login to the web interface is possible
You are affected if any of the listed products are installed with a version matching exactly 2.0, 7.0, 8.0, 9.0, 1.1, 1.2, or 1.3 and the web interface with user authentication is enabled.

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 dataImplement and enforce proper server-side authorization checks on all web interface actions to validate user privilege levels; apply vendor-provided patches for affected versions.
