CVE-2025-9976: 3DEXPERIENCE Platform RCE Vulnerability

CVE-2025-9976 Overview

CVE-2025-9976 is a critical OS Command Injection vulnerability affecting the Station Launcher App component in the Dassault Systèmes 3DEXPERIENCE platform. This vulnerability allows an attacker to inject and execute arbitrary operating system commands on the user's machine, potentially leading to complete system compromise. The flaw exists in releases spanning from 3DEXPERIENCE R2022x through 3DEXPERIENCE R2025x.

Critical Impact

Technical Details for CVE-2025-9976

Vulnerability Analysis

This vulnerability is classified as CWE-78 (Improper Neutralization of Special Elements used in an OS Command), commonly known as OS Command Injection. The Station Launcher App within the 3DEXPERIENCE platform fails to properly sanitize user-supplied input before passing it to an operating system shell for execution.

Command Injection vulnerabilities occur when an application constructs shell commands using untrusted data without adequate validation or escaping. In this case, the Station Launcher App appears to incorporate external input directly into system command strings, allowing attackers to append or inject their own commands using shell metacharacters such as ;, |, &&, or backticks.

The scope change indicator in the vulnerability assessment means that exploitation can affect resources beyond the vulnerable component's security scope, potentially impacting the entire host system and other applications running on the same machine.

Root Cause

The root cause of CVE-2025-9976 lies in insufficient input validation and sanitization within the Station Launcher App. When the application processes certain input parameters, it fails to neutralize shell metacharacters before incorporating them into OS commands. This allows specially crafted input to break out of the intended command context and execute arbitrary commands with the privileges of the application process.

The 3DEXPERIENCE platform is widely used in enterprise environments for product lifecycle management, design, and manufacturing operations. The Station Launcher App component likely handles application launching and session management, making the command injection vector particularly dangerous as it operates with user-level privileges on the host system.

Attack Vector

The attack can be executed over the network and requires low privileges along with user interaction. An attacker could exploit this vulnerability by:

1. Crafting malicious input containing OS command injection payloads
2. Tricking an authenticated user into interacting with the malicious payload through the Station Launcher App
3. The injected commands execute with the privileges of the 3DEXPERIENCE application process

Typical command injection payloads might include shell metacharacters to chain additional commands. For example, injecting command separators allows execution of arbitrary system commands beyond the intended functionality of the application. See the 3DS Security Advisory for technical details.

Detection Methods for CVE-2025-9976

Indicators of Compromise

• Unusual child processes spawned by the Station Launcher App or 3DEXPERIENCE components
• Unexpected outbound network connections from 3DEXPERIENCE processes
• Anomalous command-line arguments containing shell metacharacters (;, |, &&, $())
• System log entries showing command execution failures or unexpected shell commands

Detection Strategies

• Monitor process creation events for 3DEXPERIENCE components spawning unexpected child processes such as cmd.exe, powershell.exe, bash, or sh
• Implement application whitelisting to detect and block unauthorized executables launched from the 3DEXPERIENCE installation directory
• Deploy endpoint detection and response (EDR) solutions like SentinelOne to identify command injection attack patterns
• Review web server and application logs for request parameters containing shell metacharacters

Monitoring Recommendations

• Enable verbose logging for the 3DEXPERIENCE platform and Station Launcher App components
• Configure SIEM rules to alert on process ancestry anomalies involving 3DEXPERIENCE applications
• Implement network monitoring to detect command-and-control communications originating from engineering workstations
• Establish baseline behavior profiles for 3DEXPERIENCE users to identify anomalous activity patterns

How to Mitigate CVE-2025-9976

Immediate Actions Required

• Review the official 3DS Security Advisory for specific patch information and apply available security updates
• Restrict network access to 3DEXPERIENCE platforms to trusted networks and users only
• Implement application control policies to prevent execution of unauthorized binaries
• Increase monitoring and logging on systems running vulnerable 3DEXPERIENCE versions
• Consider temporarily disabling the Station Launcher App if not business-critical until patches are applied

Patch Information

Dassault Systèmes has published a security advisory addressing this vulnerability. Organizations running affected versions of the 3DEXPERIENCE platform (R2022x through R2025x) should consult the 3DS Security Advisory for detailed patching instructions and download the latest security updates from the Dassault Systèmes support portal.

Workarounds

• Implement network segmentation to isolate 3DEXPERIENCE systems from untrusted networks
• Apply strict input validation at the network perimeter using web application firewalls (WAF) to filter requests containing command injection patterns
• Restrict user permissions on 3DEXPERIENCE workstations to limit the impact of successful exploitation
• Deploy SentinelOne agents on affected systems for real-time behavioral detection of command injection attacks
