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 PS/IGES Parasolid Translator Component (All versions < V29.0.258), Simcenter Femap (All versions < V2512.0003), Solid Edge (All versions < V226.00 Update 03). The affected applications contains an out of bounds read vulnerability while parsing specially crafted IGS files. This could allow an attacker to crash the application or execute code in the context of the current process. (ZDI-CAN-26755)

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

This is an out-of-bounds read vulnerability in the IGES (IGS) file parser within Siemens Parasolid-based translation components used across multiple CAD products. When parsing specially crafted IGS files, the parser reads memory beyond allocated buffers, which can corrupt memory and potentially enable arbitrary code execution in the context of the running process.

MitigationUpdate affected software to vendor-supplied patched versions: PS/IGES Parasolid Translator to V29.0.258 or later, Simcenter Femap to V2512.0003 or later, and Solid Edge to V226.00 Update 03 or later. Until patches are applied, avoid opening IGS files from untrusted sources.

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. Identify installed Parasolid-based CAD products
    Check program files for Simcenter Femap, Solid Edge, or Parasolid IGES Translator installations. Look for executables like femap.exe, sedge.exe, or ps_igs_translator.exe in typical install directories (C:\Program Files\Siemens or C:\Program Files\Femap).
    Affected if Any of these Siemens CAD products are installed on the system
  2. Determine installed product version
    For Solid Edge: Open the application, go to Help > About Solid Edge to view the version (e.g., V226.00). For Simcenter Femap: Go to Help > About Femap. For Parasolid Translator: Check the application's About dialog or the executable's properties (right-click exe > Properties > Details).
    Affected if Version is 29.0.258 or prior for Parasolid Translator, 2512.0003 or prior for Simcenter Femap, or 226.00 Update 03 or prior for Solid Edge
  3. Verify IGS file handling capability is present
    Check if the Parasolid IGES translator module is available. Look for IGS file association in the system (search for .igs or .ige files in the product's translator or import folders), or check the product's import/export file format list includes IGES (.igs, .ige).
    Affected if IGES/IGS file format support is present in the installed product
  4. Confirm active use of IGES parser
    Review recent file open operations or scan the system for .igs/.ige files that may have been opened with the affected product. Check application logs or recent documents if available.
    Affected if The product has been used to open IGS files, enabling the vulnerable parser code path

The environment is affected if any of the three products (Parasolid IGES Translator, Simcenter Femap, or Solid Edge) are installed with versions at or below the patched versions and IGES file import capability is present.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Update affected software to vendor-supplied patched versions: PS/IGES Parasolid Translator to V29.0.258 or later, Simcenter Femap to V2512.0003 or later, and Solid Edge to V226.00 Update 03 or later. Until patches are applied, avoid opening IGS files from untrusted sources.

Recommended fix High confidence

PS/IGES Parasolid Translator Component V29.0.258 | Simcenter Femap V2512.0003 | Solid Edge V226.00 Update 03

  1. Identify which Siemens product(s) are in use: PS/IGES Parasolid Translator Component, Simcenter Femap, or Solid Edge
  2. For PS/IGES Parasolid Translator Component: upgrade to version V29.0.258 or later
  3. For Simcenter Femap: upgrade to version V2512.0003 or later
  4. For Solid Edge: upgrade to version V226.00 Update 03 or later
  5. Obtain the updated version from official Siemens channels (Siemens Support Center or software update mechanism)
  6. After installation, verify the version matches or exceeds the fixed release
  7. Test with legitimate IGS/IGES files to ensure normal functionality
Caveat Security update with version bumps; no functional breaking changes expected for normal CAD operations
