CVE-2024-3301
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 unsafe .NET object deserialization vulnerability in DELMIA Apriso Release 2019 through Release 2024 could lead to post-authentication remote code execution.
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 confidenceDELMIA Apriso contains an unsafe .NET object deserialization vulnerability allowing authenticated attackers to execute arbitrary code remotely. The vulnerability exists in versions 2019 through 2024 and stems from insecure handling of deserialized .NET objects without proper validation, enabling remote code execution after authentication.

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 DELMIA Apriso installed versionLocate the DELMIA Apriso installation directory and check version information in the application metadata, about dialog, or installation logs. Common locations include the program files directory or the application's configuration files.Affected if The installed version falls within the 2019 through 2024 release range.
-
Determine if web services or API endpoints are exposedReview the application's configuration files (such as web.config or app.config) and IIS settings if hosted on IIS. Look for exposed .NET remoting endpoints, WCF services, or ASMX web services that handle serialized data.Affected if The application exposes web services or API endpoints that accept serialized .NET objects without explicit mention of secure deserialization configuration.
-
Check authentication and authorization configurationExamine the authentication settings in the web.config or application configuration to determine if authentication is enforced on deserialization endpoints. Verify whether anonymous access or weak authentication methods are enabled.Affected if Authentication is enabled but endpoint-level authorization for deserialization operations is not explicitly restricted or validated.
-
Inspect application logs for deserialization activityReview DELMIA Apriso server logs, Windows Event Viewer, and application-specific log files for patterns indicating deserialization operations. Look for unusual serialized data handling or exception messages related to object deserialization.Affected if Logs show deserialization activity occurring without explicit validation traces or when unexpected serialized object types are being processed.
If DELMIA Apriso version is 2019 through 2024 AND the application exposes web services or endpoints that handle .NET serialized objects, the environment is likely affected by this 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 dataApply vendor-provided patches for DELMIA Apriso. Until patches are available, minimize network exposure, enforce strict access controls, and monitor for suspicious deserialization activity.
