Security readout for executives and security teams
Plain-English summary
Solid Edge can mishandle malicious PAR CAD files, potentially letting attacker-controlled content run code when a user opens the file. The issue is high impact but requires local user interaction, so exposure is mainly through untrusted file exchange workflows.
Executive priority
Treat this as a high-priority workstation risk for engineering environments. It is not described as remotely exploitable without user action, but successful exploitation could compromise confidentiality, integrity, and availability on affected CAD systems.
Technical view
CVE-2023-24557 is a CWE-125 out-of-bounds read past an allocated structure while parsing crafted PAR files in Solid Edge SE2022 and SE2023. Siemens reports possible code execution in the current process. CVSS v3.1 is 7.8 high with local attack vector and required user interaction.
Likely exposure
Organizations using Siemens Solid Edge SE2022 before V222.0MP12 or Solid Edge SE2023 before V223.0Update2 are exposed, especially teams receiving external PAR files from suppliers, customers, or partners.
Exploitation context
The bundled sources do not show CISA KEV listing or active exploitation. The CVSS vector includes E:P, indicating proof-of-concept maturity, but exploitation still requires a user to process a crafted PAR file.
Researcher notes
Focus validation on version exposure and PAR file ingestion paths. The public description confirms parser memory-safety behavior and potential code execution, but does not provide deeper root-cause details in the bundle. Avoid assuming broader Siemens product exposure beyond listed Solid Edge versions.
Mitigation direction
- Upgrade Solid Edge SE2022 to V222.0MP12 or later.
- Upgrade Solid Edge SE2023 to V223.0Update2 or later.
- Review Siemens advisory SSA-491245 for vendor-specific guidance.
- Limit opening PAR files from untrusted or unauthenticated sources.
- Apply normal endpoint controls for CAD workstations.
Validation and detection
- Inventory Solid Edge SE2022 and SE2023 installations and versions.
- Confirm SE2022 systems are at V222.0MP12 or later.
- Confirm SE2023 systems are at V223.0Update2 or later.
- Identify workflows that accept external PAR files.
- Check security tooling coverage on CAD workstations.

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.
