Security readout for executives and security teams
Plain-English summary
CVE-2023-24559 affects Siemens Solid Edge SE2022 and SE2023 when handling crafted PAR files. If a user opens a malicious file, the application may read memory out of bounds and allow code execution in the current process. This is most relevant to CAD workstations exchanging part files with outside parties.
Executive priority
Treat this as high priority for engineering endpoint patching. The business risk is compromise through malicious CAD files, not broad internet exposure. Prioritize teams that exchange Solid Edge files externally.
Technical view
The issue is CWE-125 out-of-bounds read while parsing PAR files in Solid Edge SE2022 before V222.0MP12 and SE2023 before V223.0Update2. CVSS 3.1 is 7.8: local attack vector, low complexity, no privileges required, user interaction required, and high confidentiality, integrity, and availability impact.
Likely exposure
Organizations using affected Solid Edge SE2022 or SE2023 builds are exposed, especially where engineers open externally supplied PAR files. Server-side exposure is not indicated by the sources.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. Exploitation requires user interaction: opening a specially crafted PAR file in an affected Solid Edge installation.
Researcher notes
Focus validation on version thresholds and PAR file workflows. The CVSS vector indicates local execution with required user interaction, no privileges, and high impact. Do not assume exploit availability or active exploitation from the provided evidence.
Mitigation direction
- Upgrade Solid Edge SE2022 to V222.0MP12 or later.
- Upgrade Solid Edge SE2023 to V223.0Update2 or later.
- Review Siemens SSA-491245 for exact vendor remediation guidance.
- Limit opening PAR files from untrusted sources until patched.
- Prioritize CAD workstations handling partner, supplier, or customer files.
Validation and detection
- Inventory installed Solid Edge versions across engineering endpoints.
- Confirm SE2022 builds are V222.0MP12 or later.
- Confirm SE2023 builds are V223.0Update2 or later.
- Check software deployment records for successful update completion.
- Review exposure to externally received PAR files.

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.
