Remote Code Execution in Dassault Systèmes DELMIA Apriso via Deserialization of Untrusted Data
CVE-2025-5086 is a critical deserialization of untrusted data vulnerability in Dassault Systèmes DELMIA Apriso. It affects DELMIA Apriso Release 2020 through Release 2025, including versions up to and including 2020 SP4, 2021 SP3, 2022 SP3, 2023 SP3, 2024 SP1, and 2025 SP1. The flaw is remotely reachable over the network and, according to vendor and downstream reporting, can be exploited without authentication or user interaction to achieve remote code execution on the vulnerable host. Public reporting does not identify the specific vulnerable function or code path, but the issue is consistently described as unsafe deserialization of attacker-controlled data within the Apriso application. CISA added the vulnerability to the KEV catalog, and multiple reports state there is evidence of active exploitation in the wild.
