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 < V33.1.264), Parasolid V34.0 (All versions < V34.0.252), Parasolid V34.1 (All versions < V34.1.242), Parasolid V35.0 (All versions < V35.0.170), Solid Edge SE2022 (All versions < V222.0MP12), Solid Edge SE2022 (All versions), Solid Edge SE2023 (All versions < V223.0Update2). The affected applications contain an out of bounds write past the end of an allocated structure while parsing specially crafted X_B files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-19070)

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 and Solid Edge when parsing specially crafted X_B files. The parsing logic writes past the end of an allocated memory structure, potentially allowing an attacker to achieve code execution in the context of the current process.

MitigationApply vendor-supplied patches to reach the fixed versions: Parasolid V33.1.264, V34.0.252, V34.1.242, V35.0.170; Solid Edge V222.0MP12 or V223.0Update2. Until patched, restrict handling of X_B 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 if Siemens Parasolid is installed
    Check the installed Parasolid version through the application's about dialog, version information in the software itself, or the program's file properties (right-click the executable > Properties > Details). Record the full version number (e.g., 33.1.100).
    Affected if The installed version falls within these ranges: >= 33.1.0 and < 33.1.264; OR >= 34.0.0 and < 34.0.252; OR >= 34.1.0 and < 34.1.242; OR >= 35.0.0 and < 35.0.170.
  2. Identify if Siemens Solid Edge is installed
    Check the installed Solid Edge version through the application's about dialog, help menu, or the program's file properties. Record the version name (Se2022, Se2023) or number (e.g., 223.0).
    Affected if The installed version is Solid Edge Se2022 (any version), Solid Edge Se2023 (any version), or version 223.0 specifically.
  3. Determine if X_B file parsing is used
    Check whether the system or application is configured to process or import X_B format files. Look for recent .X_B file imports, file handlers, or integration settings that enable X_B file handling in the software.
    Affected if X_B file parsing capability is enabled and the software processes X_B files from any source.
  4. Review recent X_B file processing activity
    Check application logs, recent file history, or document management systems for evidence of .X_B file imports or operations performed in the affected timeframe.
    Affected if X_B files have been opened, imported, or processed by the affected software.

You are affected if Parasolid version is within any of the four vulnerable ranges OR Solid Edge is Se2022/Se2023/223.0, AND X_B file parsing is enabled or X_B files have been processed.
