CVE-2023-1514
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 vulnerability exists in the component RTU500 Scripting interface. When a client connects to a server using TLS, the server presents a certificate. This certificate links a public key to the identity of the service and is signed by a Certification Authority (CA), allowing the client to validate that the remote service can be trusted and is not malicious. If the client does not validate the parameters of the certificate, then attackers could be able to spoof the identity of the service. An attacker could exploit the vulnerability by using faking the identity of a RTU500 device and intercepting the messages initiated via the RTU500 Scripting interface.
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 confidenceThe RTU500 Scripting interface fails to properly validate TLS certificate parameters on the client side during server authentication. When a client connects to a server, the certificate is not verified against expected parameters, allowing an attacker to impersonate a legitimate RTU500 device by presenting a fraudulent certificate and intercepting communications.

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 version of RTU500 Scripting InterfaceLocate and inspect the scripting interface installation directory or use system inventory tools to find the installed version number (typically displayed in file properties, About dialog, or version metadata files)Affected if The version matches 1.0.1.30, 1.0.2, or 1.1.1
-
Confirm TLS client connections are in useReview the scripting interface configuration files or logs to determine if outbound TLS connections to servers are enabled or being usedAffected if TLS client connections to remote servers are configured or actively used
-
Inspect TLS certificate validation configurationExamine the RTU500 Scripting Interface configuration files, settings, or API parameters related to TLS certificate verification (such as verify_peer, ca_file, or certificate chain validation flags)Affected if Certificate validation is disabled, not enforced, or set to bypass trust checks
-
Check for custom or missing certificate authority settingsLook for configuration entries specifying trusted Certificate Authorities or certificate store paths used during TLS handshakeAffected if No trusted CA bundle is configured or validation relies on default system settings that may not be properly enforced
The environment is affected if the installed RTU500 Scripting Interface version is 1.0.1.30, 1.0.2, or 1.1.1 and TLS client connections to servers are enabled without proper certificate validation enforcement.

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 dataEnable and enforce proper TLS certificate validation on the client, including verification of certificate chain, hostname matching, and validity period against trusted Certificate Authorities.
