Overview
A critical vulnerability, identified as CVE-2025-40762, has been discovered in Siemens’ Simcenter Femap software. This vulnerability affects two versions of the software: V2406 (All versions < V2406.0003) and V2412 (All versions < V2412.0002). The impact of this vulnerability is significant, as it could potentially allow an attacker to execute arbitrary code in the context of the current process, leading to total system compromise or data leakage. This vulnerability is particularly concerning due to the widespread use of Simcenter Femap in various industries, including automotive, aerospace, and electronics. Companies using the affected versions of this software are at risk and need to take swift action to mitigate the threat.

Product | Affected Versions
Simcenter Femap | V2406 (All versions < V2406.0003) Simcenter Femap | V2412 (All versions < V2412.0002) How the Exploit Works
The vulnerability lies within the application’s handling of STP files. An attacker can exploit this vulnerability by crafting a malicious STP file that, when parsed by the application, triggers an out-of-bounds write error. This error can cause memory corruption, allowing an attacker to execute arbitrary code in the context of the current process.
Conceptual Example Code
Here is a conceptual example of a shell command that could potentially exploit this vulnerability:
# Crafting a malicious STP file
echo "malicious_payload" > exploit.stp
# Sending the malicious STP file to the target system
scp exploit.stp user@target:/path/to/femap/input/Please note that the above example is purely conceptual and serves to illustrate the potential method of exploitation. The actual exploit would require a detailed understanding of the Simcenter Femap’s STP file parsing mechanism and the specific memory layout to successfully execute arbitrary code.
