Full Report
Siemens Teamcenter Visualization contains multiple file parsing vulnerabilities that could be triggered when the application reads files in WRL format. If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution. Siemens has released new versions for the affected products and recommends to update to the latest versions.
Analysis Summary
# Vulnerability: Multiple WRL File Parsing Vulnerabilities in Teamcenter Visualization
## CVE Details
- **CVE IDs:** CVE-2024-45463 through CVE-2024-45476, CVE-2024-52565 through CVE-2024-52574, CVE-2024-53041, CVE-2024-53242 (26 Identifiers total)
- **CVSS Score:**
- CVSS v3.1: 7.8 (High)
- CVSS v4.0: 7.3 (High)
- **CWE:**
- CWE-121 (Stack-based Buffer Overflow)
- CWE-125 (Out-of-bounds Read)
- CWE-787 (Out-of-bounds Write)
## Affected Systems
- **Products:** Siemens Teamcenter Visualization
- **Versions:**
- V14.2: All versions prior to V14.2.0.14
- V14.3: All versions prior to V14.3.0.12
- **Configurations:** Systems where users open VRML (.WRL) format files using the affected software.
## Vulnerability Description
Multiple flaws exist in how Teamcenter Visualization parses files in the WRL (Virtual Reality Modeling Language) format. The application suffers from stack-based buffer overflows, out-of-bounds reads, and out-of-bounds writes when processing specially crafted WRL files. These memory corruption issues occur when the application fails to properly validate the input data structure or length before copying it to memory or reading from an allocated buffer.
## Exploitation
- **Status:** Not currently reported as exploited in the wild; PoC status not explicitly confirmed, though researchers (ZDI) have identified the flaws.
- **Complexity:** Low (CVSS 3.1) to Medium (CVSS 4.0).
- **Attack Vector:** Local. The attack requires user interaction (UI:R/UI:P), specifically tricking a user into opening a malicious file.
## Impact
- **Confidentiality:** High (Potential to read sensitive memory or execute arbitrary code).
- **Integrity:** High (Potential for arbitrary code execution).
- **Availability:** High (Application crash or system compromise).
## Remediation
### Patches
Siemens recommends updating affected installations to the following versions:
- **Teamcenter Visualization V14.2:** Update to V14.2.0.14 or later.
- **Teamcenter Visualization V14.3:** Update to V14.3.0.12 or later.
### Workarounds
- Limit the opening of WRL files from untrusted or unknown sources.
- Apply general "Defense in Depth" principles by reducing user privileges to prevent widespread impact from code execution.
## Detection
- **Indicators of Compromise:** Unexpected application crashes (Access Violations) when opening 3D model files.
- **Detection methods and tools:** Use endpoint detection and response (EDR) tools to monitor for unusual child processes spawned by Teamcenter Visualization (e.g., cmd.exe or powershell.exe). Static analysis or sandboxing of incoming .WRL files can identify malformed structures typical of these exploits.
