Security readout for executives and security teams
Plain-English summary
A malicious Parasolid PAR file can trigger a memory parsing flaw in affected Siemens Parasolid and Solid Edge versions. If a user opens the file, the attacker may run code with that user’s process privileges, creating data theft, tampering, or workstation compromise risk.
Executive priority
Treat as a high-priority workstation and engineering-tool update. Business urgency is highest where CAD users routinely open external PAR files or where engineering workstations access sensitive intellectual property.
Technical view
CVE-2023-25140 is a CWE-125 out-of-bounds read past an allocated structure during crafted PAR file parsing. Siemens lists affected Parasolid V34.0, V34.1, V35.0, V35.1, and Solid Edge SE2022 versions below specified maintenance releases. CVSS 3.1 is 7.8 with local attack vector and required user interaction.
Likely exposure
Exposure is most likely in engineering or design environments using the listed Siemens Parasolid or Solid Edge SE2022 versions, especially where users receive PAR files from customers, suppliers, or external collaborators.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. The CVSS vector indicates proof-of-concept exploit maturity, but exploitation requires user interaction: opening a specially crafted PAR file locally.
Researcher notes
Evidence is limited to Siemens and CVE records. Do not infer other affected CAD products. Validation should focus on version discovery, PAR file exposure paths, and whether vulnerable parsers are present in deployed Siemens components.
Mitigation direction
- Update Parasolid V34.0 to V34.0.254 or later.
- Update Parasolid V34.1 to V34.1.242 or later.
- Update Parasolid V35.0 to V35.0.170 or later.
- Update Parasolid V35.1 to V35.1.150 or later.
- Update Solid Edge SE2022 to V222.0MP12 or later.
- Restrict untrusted PAR file handling until Siemens guidance is applied.
Validation and detection
- Inventory Siemens Parasolid and Solid Edge SE2022 installations and embedded deployments.
- Compare installed versions against Siemens fixed-version thresholds.
- Review engineering file-ingest workflows for externally supplied PAR files.
- Confirm endpoint controls cover CAD workstations handling supplier files.
- Check Siemens SSA-491245 and SSA-836777 for environment-specific guidance.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
