X_T File Parsing Vulnerabilities in Simcenter Femap before V2023.1

Auth RequiredNone
ComplexityLow
User InteractionRequired
Summary
Simcenter Femap versions before 2023.1 contain out-of-bounds read and write vulnerabilities in the X_T file parser (CWE-125, CWE-787). When a user opens a specially crafted X_T file, these memory safety issues can be exploited to achieve remote code execution in the application's process context. Siemens has released version 2023.1 with fixes for these vulnerabilities.
What this means
What could happen
If a user opens a malicious X_T file in Simcenter Femap, an attacker could execute arbitrary code on that workstation with the same privileges as the user running the application.
Who's at risk
CAD/CAE engineers and simulation specialists using Simcenter Femap for finite element analysis and modeling. This affects engineering workstations in manufacturing, automotive, aerospace, and product design organizations.
How it could be exploited
An attacker creates a malicious X_T format file and tricks a user into opening it in Simcenter Femap. The application reads the file without proper bounds checking, triggering out-of-bounds memory access. This allows the attacker to write code into memory and execute it in the application's process context.
Prerequisites
- User must open a malicious X_T file in Simcenter Femap
- Simcenter Femap must be installed and in use
- No special credentials or network access required
