Security readout for executives and security teams
Plain-English summary
Solid Edge can be compromised when a user opens a malicious PAR part file. The flaw affects older SE2022 and SE2023 builds and can let attacker-controlled file content run code as the current user. The main business risk is CAD workstations processing files from partners, suppliers, or email before patching.
Executive priority
Treat this as a high-priority workstation patching issue for engineering and design teams. It is not described as remotely exploitable over the network, but externally exchanged CAD files make user-assisted compromise plausible in normal business workflows.
Technical view
CVE-2023-24553 is a CWE-125 out-of-bounds read in Siemens Solid Edge PAR file parsing. A specially crafted PAR file can trigger memory access past an allocated structure and may allow code execution in the current process. CVSS 3.1 is 7.8 with local attack vector, low complexity, no privileges, and required user interaction.
Likely exposure
Exposure is limited to organizations running Solid Edge SE2022 before V222.0MP12 or Solid Edge SE2023 before V223.0Update2. Risk is higher where users regularly open externally supplied PAR files from customers, vendors, or collaboration platforms.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not marked KEV. Exploitation requires user interaction: a victim must open or parse a specially crafted PAR file in an affected Solid Edge version.
Researcher notes
The source bundle identifies affected versions, file type, weakness class, CVSS vector, and Siemens advisory reference. It does not provide public exploit evidence, detailed root-cause analysis, or compensating controls beyond moving past the fixed version thresholds.
Mitigation direction
- Update Solid Edge SE2022 to V222.0MP12 or later, if still deployed.
- Update Solid Edge SE2023 to V223.0Update2 or later.
- Restrict unexpected PAR files from email, web downloads, and external collaboration portals.
- Open externally supplied PAR files only on managed, monitored workstations until updated.
- Check Siemens ProductCERT guidance for any environment-specific recommendations.
Validation and detection
- Inventory Solid Edge installations and record exact SE2022 or SE2023 build levels.
- Confirm no deployed SE2022 versions are below V222.0MP12.
- Confirm no deployed SE2023 versions are below V223.0Update2.
- Review CAD file intake workflows for externally supplied PAR files.
- Check endpoint telemetry for Solid Edge crashes or alerts involving untrusted 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.
