Security readout for executives and security teams
Plain-English summary
This is a critical remote code execution issue in Dassault Systèmes DELMIA Apriso releases 2020 through 2025. If an exposed Apriso system processes malicious serialized data, an attacker could potentially run code on the server without authentication or user interaction.
Executive priority
Treat this as urgent for any affected Apriso deployment. KEV status and reported exploit attempts raise business risk beyond theoretical severity. Focus first on exposed systems, confirm vendor remediation, and track completion through vulnerability management.
Technical view
CVE-2025-5086 is a CWE-502 deserialization of untrusted data flaw affecting DELMIA Apriso Release 2020 Golden through Release 2025 Golden. CVSS 3.1 is 9.0 with network attack vector, high complexity, no privileges, no user interaction, changed scope, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to the listed DELMIA Apriso releases; other versions are marked unaffected in the supplied record. Network-reachable Apriso deployments deserve priority because the CVSS vector indicates remote, unauthenticated exploitation without user interaction.
Exploitation context
The source bundle marks this CVE as CISA KEV, supporting known exploitation. The SANS ISC reference reports exploit attempts. The bundle does not provide exploit details, affected endpoints, indicators, or fixed-version information.
Researcher notes
Evidence supports critical impact and known exploitation, but public details in the supplied bundle are limited. Do not assume exploit mechanics, target paths, or patch levels beyond vendor guidance. Validation should focus on version exposure, reachability, and vendor advisory tracking.
Mitigation direction
- Check Dassault Systèmes advisories for the official fix or supported mitigation.
- Prioritize remediation for internet-facing or broadly reachable Apriso systems.
- Restrict network access to Apriso until vendor guidance is applied.
- Increase monitoring for suspicious unauthenticated Apriso traffic.
- Document risk acceptance if remediation cannot occur immediately.
Validation and detection
- Inventory all DELMIA Apriso deployments and record exact release versions.
- Compare versions against Release 2020 Golden through Release 2025 Golden.
- Check whether each deployment is internet-facing or reachable by untrusted networks.
- Review CISA KEV status and any vendor remediation deadlines.
- Review application and perimeter logs for suspicious Apriso access attempts.

Deserialization of Untrusted Data
Deserialization of Untrusted Data represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
