CVE-2024-52570 Overview
CVE-2024-52570 is an out-of-bounds write vulnerability [CWE-787] affecting Siemens Teamcenter Visualization and Tecnomatix Plant Simulation. The flaw exists in the WRL file parser used by these applications. An attacker can craft a malicious WRL file that, when opened by a user, triggers memory corruption and enables code execution in the context of the current process. The issue was reported through the Zero Day Initiative as ZDI-CAN-24365.
Critical Impact
Successful exploitation allows arbitrary code execution in the context of the affected process, compromising confidentiality, integrity, and availability of the engineering workstation.

Technical Details for CVE-2024-52570
Vulnerability Analysis
The vulnerability resides in the WRL (VRML) file parsing routines shared by Teamcenter Visualization and Tecnomatix Plant Simulation. WRL files describe 3D scenes and geometry using structured text nodes. The parser writes attacker-controlled data past the bounds of an allocated buffer when processing specially crafted content.
An attacker leverages this out-of-bounds write to corrupt adjacent memory structures. By shaping the overwrite, the attacker can hijack control flow and execute arbitrary code within the process. Exploitation requires user interaction: the target must open the malicious WRL file in a vulnerable application.
The vulnerability is classified under [CWE-787: Out-of-bounds Write]. It carries an EPSS probability of 0.236% (14.66th percentile), indicating low observed exploitation activity to date. No public proof-of-concept exploit has been released.
Root Cause
The root cause is missing or insufficient bounds validation during WRL file deserialization. The parser trusts size or index fields embedded in the file without verifying they fall within the allocated destination buffer. Malformed geometry, coordinate arrays, or field descriptors trigger writes beyond the intended region.
Attack Vector
The attack vector is local and requires user interaction. An attacker delivers the malicious .wrl file via email, shared network location, or third-party 3D model repository. When an engineer opens the file in a vulnerable Teamcenter Visualization or Tecnomatix Plant Simulation client, the parser processes attacker-controlled input and triggers the out-of-bounds write.
Because engineering workstations frequently exchange CAD and simulation assets, WRL files are a plausible delivery format for targeted intrusions against industrial and manufacturing environments. Refer to the Siemens Security Advisory SSA-824503 for the vendor's technical description.
Detection Methods for CVE-2024-52570
Indicators of Compromise
- Unexpected .wrl files delivered via email attachments, external drives, or downloaded from untrusted sources to engineering workstations.
- Crashes or abnormal termination of Tcvis.exe, PlantSimulation.exe, or related Siemens processes shortly after opening a 3D asset.
- Child processes such as cmd.exe, powershell.exe, or script interpreters spawned by Teamcenter Visualization or Tecnomatix Plant Simulation binaries.
- Outbound network connections initiated by the Siemens application processes to unfamiliar destinations following WRL file open events.
Detection Strategies
- Monitor process lineage for Teamcenter Visualization and Plant Simulation executables, alerting on unexpected child processes or shell invocations.
- Deploy YARA rules or file-format inspection to flag WRL files with malformed headers, oversized array declarations, or anomalous field structures.
- Correlate application crash telemetry (Windows Error Reporting, WER) with recent file open events on .wrl extensions.
Monitoring Recommendations
- Track file drops of .wrl extensions across engineering workstations and file shares, correlating source with expected internal workflows.
- Enable memory-corruption exploit telemetry (CFG, DEP, ASLR violations) on hosts running affected Siemens applications.
- Log and review inbound email and web downloads containing 3D model formats destined for OT engineering users.
How to Mitigate CVE-2024-52570
Immediate Actions Required
- Update Teamcenter Visualization and Tecnomatix Plant Simulation to the fixed versions listed in the Siemens advisories.
- Restrict WRL file handling on engineering workstations to files originating from trusted internal sources only.
- Enforce email and web gateway policies that quarantine or inspect 3D model file types delivered from external senders.
- Educate engineering staff not to open unsolicited .wrl files or 3D assets from unverified sources.
Patch Information
Siemens released fixed versions across all affected product lines. Upgrade Teamcenter Visualization V14.2 to V14.2.0.14 or later, V14.3 to V14.3.0.12 or later, V2312 to V2312.0008 or later, and V2406 to V2406.0005 or later. Upgrade Tecnomatix Plant Simulation V2302 to V2302.0018 or later and V2404 to V2404.0007 or later. Full details are available in the Siemens Security Advisory SSA-824503 and Siemens Security Advisory SSA-645131.
Workarounds
- Avoid opening WRL files from untrusted or unverified sources until patches are applied.
- Apply application allowlisting to restrict which users can launch Teamcenter Visualization and Plant Simulation binaries.
- Segment engineering workstations from general corporate email and web browsing to reduce exposure to malicious file delivery.
- Enable operating-system exploit mitigations (DEP, ASLR, CFG) and endpoint exploit-prevention controls on hosts running affected Siemens software.
