Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability has been identified in Parasolid V33.1 (All versions < V33.1.262), Parasolid V33.1 (All versions >= V33.1.262 < V33.1.263), Parasolid V34.0 (All versions < V34.0.252), Parasolid V34.1 (All versions < V34.1.242), Parasolid V35.0 (All versions < V35.0.161), Parasolid V35.0 (All versions >= V35.0.161 < V35.0.164), Simcenter Femap V2022.1 (All versions < V2022.1.3), Simcenter Femap V2022.2 (All versions < V2022.2.2). The affected application contains an out of bounds write past the end of an allocated buffer while parsing specially crafted X_T files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-17494)

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Out-of-bounds write vulnerability in Parasolid CAD kernel and Simcenter Femap when parsing specially crafted X_T files, allowing arbitrary code execution in the context of the current process.

MitigationUpgrade to the patched Parasolid versions (V33.1.263, V34.0.252, V34.1.242, or V35.0.164) and Simcenter Femap versions (V2022.1.3 or V2022.2.2).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check Simcenter Femap version
    Open Simcenter Femap and navigate to Help > About, or check the installed version in Windows Programs and Features. Compare the version number to the affected ranges: >= 2022.1 but < 2022.1.3, or >= 2022.2 but < 2022.2.2.
    Affected if The installed Femap version falls within the affected ranges.
  2. Check Parasolid kernel version
    Locate the Parasolid installation (commonly in Program Files or within CAD applications that bundle it) and identify the version. This may be found in the Parasolid DLL properties, or within the application's documentation. Compare to the affected ranges: >= 33.1 < 33.1.263, >= 34.0 < 34.0.252, >= 34.1 < 34.1.242, or >= 35.0 < 35.0.164.
    Affected if The Parasolid kernel version is within any of the affected version ranges.
  3. Verify X_T file parsing capability
    Determine whether Simcenter Femap or any application using the affected Parasolid version is configured to import or open X_T files. Check file associations or import settings for .x_t file type support.
    Affected if X_T file parsing is enabled or available in the environment.

You are affected if either Simcenter Femap or Parasolid (standalone or embedded) is installed with a version matching the affected ranges and X_T file parsing functionality is present.

Fixed in 33.1.26334.0.25234.1.242
Interim mitigation

Upgrade to the patched Parasolid versions (V33.1.263, V34.0.252, V34.1.242, or V35.0.164) and Simcenter Femap versions (V2022.1.3 or V2022.2.2).

Recommended fix High confidence

Simcenter Femap: V2022.1.3 or V2022.2.2; Parasolid: V33.1.263, V34.0.252, V34.1.242, or V35.0.164

  1. Identify the currently installed version of Simcenter Femap or Parasolid in your environment
  2. Navigate to the Siemens support portal (cert-portal.siemens.com) or official Siemens PLM downloads
  3. Download Simcenter Femap V2022.1.3 or later (V2022.2.2 or later) depending on your release branch
  4. If using Parasolid as a standalone component, download the corresponding fixed version: V33.1.263, V34.0.252, V34.1.242, or V35.0.164
  5. Apply the update by running the installer with appropriate administrative privileges
  6. Restart any running instances of the affected application
  7. Verify the installed version matches the fixed release by checking the application's About/Help section
