Detect CVE-2025-6204 — Dassault Systèmes DELMIA Apriso Code Injection in Splunk
Detects exploitation of CVE-2025-6204, a code injection vulnerability (CWE-94) in Dassault Systèmes DELMIA Apriso. This vulnerability allows attackers to inject and execute arbitrary code through the Apriso application layer. It is listed on CISA's Known Exploited Vulnerabilities catalog, indicating active exploitation in the wild. Successful exploitation can lead to remote code execution, lateral movement, and full compromise of manufacturing execution system (MES) environments.

Data Sources
Required Sourcetypes
False Positives & Tuning
- Authorized penetration testing activities targeting the Apriso environment
- Apriso batch processing jobs that spawn legitimate child processes with shell-like command syntax
- Administrative tooling or scripts that interact with Apriso's API using parameters resembling code injection patterns
- Monitoring agents installed on Apriso servers that execute diagnostic commands

Testing Methodology
Validate this detection against 4 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Simulate Apriso Code Injection via HTTP Request with Command Execution Payload
Expected signal: IIS access log entry with POST to /Apriso/GlobalSuite.aspx; Sysmon Event ID 1 showing cmd.exe spawned by w3wp.exe; Windows Security Event ID 4688 for cmd.exe process creation.
- Test 2Web Shell Drop Simulation via Apriso Worker Process
Expected signal: Sysmon Event ID 11 (FileCreate) for test_shell.aspx in the web root; Sysmon Event ID 1 for cmd.exe with parent w3wp.exe; Windows Security Event ID 4663 for file write to IIS directory.
- Test 3Outbound Beacon Simulation from Apriso Server Context
Expected signal: Network connection event from the Apriso process (java or tomcat) to an external/loopback destination; DNS query or direct IP connection logged by EDR or network monitoring; process execution log showing curl or wget spawned by the web application parent.
- Test 4Reconnaissance Commands Executed Post-Injection via PowerShell
Expected signal: Sysmon Event ID 1 for powershell.exe with parent w3wp.exe; Windows Security Event ID 4688 for PowerShell process; PowerShell Script Block Logging Event ID 4104 capturing the reconnaissance commands.
