Security readout for executives and security teams
Plain-English summary
CVE-2023-24556 affects Siemens Solid Edge when it opens specially crafted PAR files. A malicious file could cause code to run inside the Solid Edge process. This is primarily a workstation and file-handling risk, not a remotely reachable server flaw, but it can still matter where engineering files come from customers, suppliers, or email.
Executive priority
Prioritize patching engineering workstations that handle external CAD files. The business risk is code execution through trusted design workflows, with potential data theft, workstation compromise, or disruption to engineering operations.
Technical view
Affected Solid Edge SE2022 versions before V222.0MP12 and SE2023 versions before V223.0Update2 contain a CWE-125 out-of-bounds read while parsing PAR files. The CVSS 3.1 score is 7.8, with local attack vector, no privileges required, user interaction required, and high confidentiality, integrity, and availability impact.
Likely exposure
Exposure is most likely on engineering workstations running affected Solid Edge versions, especially where users open PAR files from external parties, shared repositories, email, or web downloads.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation. The CVSS vector includes proof-of-concept exploit maturity, but exploitation still requires a user to open a malicious PAR file locally.
Researcher notes
Key constraints are AV:L and UI:R: exploitation depends on local file parsing by the user. The source bundle identifies affected version ranges and fixed release thresholds, but does not provide deeper root-cause detail beyond the PAR parser out-of-bounds read.
Mitigation direction
- Upgrade Solid Edge SE2022 to V222.0MP12 or later.
- Upgrade Solid Edge SE2023 to V223.0Update2 or later.
- Check Siemens SSA-491245 for the official update path and guidance.
- Limit opening PAR files from untrusted external sources.
- Apply attachment and file-transfer controls for unsolicited engineering files.
Validation and detection
- Inventory Solid Edge installations and record exact SE2022 or SE2023 build versions.
- Confirm no affected workstation remains below the fixed versions.
- Review whether PAR files are accepted from external parties or email.
- Check endpoint detections for suspicious Solid Edge process behavior.
- Track remediation evidence against Siemens SSA-491245.

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.
