If a user is tricked to open a malicious file with the affected application, an attacker could leverage the vulnerability to leak information or potentially perform remote code execution in the context of the current process.\n\nSiemens recommends to update to the latest version line of Simcenter Femap and to avoid opening of untrusted files from unknown sources."
