CVE-2023-24562
📋 TL;DR
This vulnerability in Solid Edge CAD software allows attackers to execute arbitrary code by exploiting uninitialized pointer access when processing malicious PAR files. Users of Solid Edge SE2022 and SE2023 before specific updates are affected. Successful exploitation could lead to complete system compromise.
💻 Affected Systems
- Solid Edge SE2022
- Solid Edge SE2023
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining the same privileges as the Solid Edge process, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation or remote code execution when a user opens a malicious PAR file, leading to malware installation or data exfiltration.
If Mitigated
Limited impact with proper application sandboxing and user privilege restrictions, potentially containing the exploit to the Solid Edge process only.
🎯 Exploit Status
Exploitation requires user interaction to open malicious PAR files. No public exploit code is available as of analysis.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Solid Edge SE2022: V222.0MP12 or later; Solid Edge SE2023: V223.0Update2 or later
Vendor Advisory: https://cert-portal.siemens.com/productcert/pdf/ssa-491245.pdf
Restart Required: Yes
Instructions:
1. Download the latest update from Siemens support portal. 2. Close all Solid Edge applications. 3. Run the update installer with administrative privileges. 4. Restart the system after installation completes.
🔧 Temporary Workarounds
Block PAR file extensions
windowsPrevent Solid Edge from opening PAR files via group policy or application restrictions
Not applicable - configure via Group Policy or application whitelisting
User awareness training
allEducate users to avoid opening PAR files from untrusted sources
🧯 If You Can't Patch
- Implement application whitelisting to restrict execution of Solid Edge to trusted locations only
- Use endpoint protection with behavior monitoring to detect and block suspicious Solid Edge process activities
🔍 How to Verify
Check if Vulnerable:
Check Solid Edge version via Help > About Solid Edge. If version is below V222.0MP12 for SE2022 or below V223.0Update2 for SE2023, the system is vulnerable.Check Version:
