DELMIA Apriso is utilized in production processes for digitalization and monitoring, with widespread deployment in automotive, aerospace, electronics, high-tech, and industrial machinery divisions. It supports various functions, including production scheduling, quality management, resource allocation, and warehouse management.

The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning regarding a critical vulnerability, identified as CVE-2025-5086, a deserialization of untrusted data vulnerability that can lead to remote code execution. It has a CVSS score of 9.0 and an EPSS score of 68.66%, which indicate its critical severity. The remote code execution (RCE) vulnerability is in Dassault Systèmes’ DELMIA Apriso software. This manufacturing operations management (MOM) and execution (MES) solution is used by organizations worldwide.

Technical Analysis

The exploitation of CVE-2025-5086 involves sending malicious SOAP/HTTP requests to vulnerable endpoints. These requests load and execute a Base64-encoded, GZIP-compressed .NET executable embedded within the XML. Security researcher Johannes Ullrich observed these attacks originating from IP address 156.244.33[.]162.

The malicious payload has been identified as a Windows executable. Researchers have classified a similar DLL as “Trojan.MSIL.Zapchast.gen“, a program designed for cyber espionage activities such as keylogging, screenshot capture, and gathering active application lists.

Affected Products

The vulnerability affects DELMIA Apriso versions from Release 2020 through Release 2025.

Tactics, Techniques & Procedures (TTPs)

The observed attacks leverage the following MITRE ATT&CK TTPs:

• TA0002 – Execution: Attackers achieve code execution by exploiting the deserialization vulnerability.
• T1203 – Exploitation for Client Execution: This involves exploiting a vulnerability in DELMIA Apriso to execute malicious code on the server.

Indicators of Compromise

An indicator of compromise (IOC) associated with this vulnerability is the IP address 156.244.33[.]162, which has been linked to exploitation attempts.
