CVE-2024-40395
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 · uneditedAn Insecure Direct Object Reference (IDOR) in PTC ThingWorx v9.5.0 allows attackers to view sensitive information, including PII, regardless of access 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 confidenceAn Insecure Direct Object Reference (IDOR) vulnerability in PTC ThingWorx v9.5.0 allows authenticated or unauthenticated attackers to directly reference internal objects (such as database records or files) to access sensitive personally identifiable information (PII) without proper authorization validation, bypassing standard access controls.

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 ThingWorx versionCheck the ThingWorx installation directory for version information, typically found in the ThingWorxPlatform/InstalledPackages folder or by accessing the /ThingWorx/Status resource on the web serverAffected if The installed version is exactly 9.5.0
-
Verify ThingWorx web interface is exposedAccess the ThingWorx web server on the configured port (default 80/443 or 8080/8443) and confirm the application is reachableAffected if The ThingWorx web interface is accessible and responds to requests
-
Confirm authorization configurationReview the ThingWorx platform settings in ThingWorxPlatform/PlatformSettings.json or through the ThingWorx Administrator console to verify if resource-level authorization is enabledAffected if Authorization settings allow direct object reference without ownership validation or the configuration cannot be verified as enforcing strict object-level access control
If the installed ThingWorx version is 9.5.0 and the web interface is accessible without verified strict authorization controls, the environment is likely affected by this IDOR vulnerability.

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 proper authorization checks on all object references to verify the requesting user has permission to access the specific resource, regardless of the provided object identifier; enforce access control validation at every data access point.
