CVE-2025-25175
📋 TL;DR
A memory corruption vulnerability in Simcenter Femap allows attackers to execute arbitrary code by tricking users into opening malicious .NEU files. This affects all versions of Simcenter Femap V2401 before V2401.0003 and V2406 before V2406.0002. Users who open untrusted .NEU files are at risk.
💻 Affected Systems
- Simcenter Femap V2401
- Simcenter Femap V2406
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining the same privileges as the Femap user, potentially leading to data theft, lateral movement, or ransomware deployment.
Likely Case
Local privilege escalation or malware execution when users open malicious engineering files from untrusted sources.
If Mitigated
Limited impact if users only open trusted files and proper application sandboxing is in place.
🎯 Exploit Status
Exploitation requires user interaction to open malicious file. No authentication bypass needed but requires social engineering or file placement.
