CVE-2024-0220
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 · uneditedB&R Automation Studio Upgrade Service and B&R Technology Guarding use insufficient cryptography for communication to the upgrade and the licensing servers. A network-based attacker could exploit the vulnerability to execute arbitrary code on the products or sniff sensitive data.
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 confidenceB&R Automation Studio Upgrade Service and B&R Technology Guarding communicate with upgrade and licensing servers using insufficient cryptography. A network-based attacker can exploit weak or absent encryption to intercept sensitive data or inject malicious code, potentially achieving remote code execution on affected products.

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 Automation Studio versionOpen B&R Automation Studio and navigate to Help > About, or check the installed programs list in Windows Control Panel. Record the exact version number.Affected if Version is below 4.6 (e.g., 4.5.x, 4.0.x, etc.)
-
Identify installed Technology Guarding versionCheck the Technology Guarding installation directory or the Add/Remove Programs list in Windows. Record the exact version number.Affected if Version is below 1.4.0 (e.g., 1.3.x, 1.0.x, etc.)
-
Determine if Upgrade Service is configured and activeCheck the Automation Studio project settings or configuration files for Upgrade Service endpoints. Look for configured upgrade server URLs in the project or system configuration.Affected if Upgrade Service points to an upgrade server and is actively used by the automation project
-
Determine if Technology Guarding communicates with licensing serversInspect Technology Guarding configuration for licensing server URLs or endpoints. Check network logs to identify outbound connections to licensing servers.Affected if Technology Guarding is configured to communicate with licensing servers over the network
The environment is affected if either Automation Studio version is below 4.6 OR Technology Guarding version is below 1.4.0, and the respective upgrade or licensing communication feature is enabled and actively communicating with external servers.

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 data1.4.04.6
Replace weak or absent encryption with strong, modern cryptographic protocols (TLS 1.2+ with strong ciphers) for all upgrade and licensing server communications; apply vendor patches when available and segment network traffic to these servers.
