DELMIA Apriso: Deserialization of Untrusted Data
CVE-2024-3300 is a critical-severity deserialization of untrusted data vulnerability in DELMIA Apriso from Dassault Systèmes, with a CVSS 3.1 base score of 9.0 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected DELMIA Apriso versions: Release 2019 Golden through Release 2019 SP5; Release 2020 Golden through Release 2020 SP4; Release 2021 Golden through Release 2021 SP3, and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 2.87% chance of exploitation within 30 days, higher than 87% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Check which version of DELMIA Apriso you run against the affected versions below, and install the vendor's latest release.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
An unsafe .NET object deserialization vulnerability in DELMIA Apriso Release 2019 through Release 2024 could lead to pre-authentication remote code execution.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Deserialization of Untrusted Data
The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.
How developers prevent this class of flaw
- If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
- When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
- Explicitly define a final object() to prevent deserialization.
