CVE-2021-22782
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 · uneditedMissing Encryption of Sensitive Data vulnerability exists in EcoStruxure Control Expert (all versions prior to V15.0 SP1, including all versions of Unity Pro), EcoStruxure Process Expert (all versions, including all versions of EcoStruxure Hybrid DCS), and SCADAPack RemoteConnect for x70, all versions, that could cause an information leak allowing disclosure of network and process information, credentials or intellectual property when an attacker can access a 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 · moderate confidenceMissing encryption in project files for EcoStruxure Control Expert, Process Expert, and SCADAPack RemoteConnect allows attackers with file access to read sensitive data including credentials, network configuration, process information, and intellectual property. The vulnerability stems from project files storing sensitive data in plaintext rather than using encryption.

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 installed Schneider Electric productCheck the installed programs list or product documentation to determine if EcoStruxure Control Expert, Process Expert, or SCADAPack RemoteConnect is installed on the systemAffected if Any of these three products are installed
-
Check Control Expert versionLook in the Control Expert installation directory or program properties for the version number. Compare it to the affected range: versions < 15.0 or exactly 15.0Affected if Control Expert version is 15.0 or earlier than 15.0
-
Confirm affected product typeDetermine if the installed product is Process Expert or SCADAPap RemoteConnect - these are affected in all versionsAffected if Process Expert or RemoteConnect of any version is installed
-
Locate project filesSearch for project files associated with the installed product - these are typically stored in user-defined project directories and have product-specific extensionsAffected if Project files exist and the product is one of the three affected products
-
Inspect project file contentsOpen or examine a project file in a text editor to check if sensitive data such as credentials, network configuration, or process information appears in plaintextAffected if Project files contain plaintext sensitive data without encryption
The environment is affected if EcoStruxure Control Expert (version 15.0 or earlier), Process Expert (any version), or SCADAPack RemoteConnect (any version) is installed and contains project files with unencrypted sensitive data.

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 data15.0
Upgrade EcoStruxure Control Expert to V15.0 SP1 or later; for Process Expert and SCADAPack RemoteConnect, implement encryption for project file storage or restrict access to project files as a compensating control until a patched version is available.
