Technical details

A Deserialization of Untrusted Data vulnerability (CWE-502) exists in the Station Launcher App component of the Dassault Systèmes 3DEXPERIENCE platform. The flaw allows an unauthenticated remote attacker to send specially crafted serialized data to the application, which, when processed, results in arbitrary code execution with the privileges of the application. The vulnerability is highly critical as it requires no user interaction or prior authentication and has a wide impact across releases R2023x through R2026x. Remediation information is available through the vendor's trust center.
