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 path traversal vulnerability was discovered in multiple Pilz products. An unauthenticated local attacker could use a zipped, malicious configuration file to trigger arbitrary file writes ('zip-slip'). File writes do not affect confidentiality or availability.

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 · moderate confidence

This is a zip-slip vulnerability in Pilz industrial automation products where a path traversal occurs during extraction of zipped configuration files. An unauthenticated local attacker can craft a malicious zip file containing paths with '..' sequences to write files to arbitrary locations outside the intended extraction directory.

MitigationApply vendor-provided patches or firmware updates for affected Pilz products. Implement strict validation of file paths within zip archives before extraction, ensuring extracted paths resolve within the intended target directory.

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 Pilz industrial automation products
    Open Windows Control Panel > Programs and Features, or check C:\Program Files and C:\Program Files (x86) for Pilz directories. Look for: PAS 4000, Pascal, PASconnect, PASmotion, or Pnozmulti Configurator.
    Affected if Any of these Pilz products are present on the system
  2. Determine installed version of PAS 4000
    If installed, right-click the application shortcut, select Properties, then look in the Details tab for Version info. Alternatively, check the program's Help > About dialog.
    Affected if Version is lower than 1.25.0
  3. Determine installed version of Pascal
    Check application Properties > Details tab, or look in the installation directory for a version.txt or about file.
    Affected if Version is 1.9.1 or lower
  4. Determine installed version of PASconnect
    Check application Properties > Details tab or Help > About dialog.
    Affected if Version is lower than 1.4.0
  5. Determine installed version of PASmotion
    Check application Properties > Details tab or Help > About dialog.
    Affected if Version is lower than 1.4.1
  6. Determine installed version of Pnozmulti Configurator
    Check application Properties > Details tab or Help > About dialog. Note that there are two version branches: 10.x and 11.x.
    Affected if Version is lower than 10.14.4 (for 10.x branch) or lower than 11.2.0 (for 11.x branch)

The system is affected if any Pilz product from the list is installed with a version falling within the specified vulnerable ranges.

Upgrade available Upgrade to 1.4.0 / 1.4.1 / 1.25.0 or later
Fixed in 1.4.01.4.11.25.0
Interim mitigation

Apply vendor-provided patches or firmware updates for affected Pilz products. Implement strict validation of file paths within zip archives before extraction, ensuring extracted paths resolve within the intended target directory.

Recommended fix Moderate confidence

Pas 4000: 1.25.0+ | Pascal: 1.9.2+ | Pasconnect: 1.4.0+ | Pasmotion: 1.4.1+ | Pnozmulti Configurator: 10.14.4+ or 11.2.0+

  1. 1. Identify the specific Pilz product(s) in use from the affected list: Pas 4000, Pascal, Pasconnect, Pasmotion, or Pnozmulti Configurator
  2. 2. Determine the current installed version of the affected product(s)
  3. 3. For Pas 4000: upgrade to version 1.25.0 or higher
  4. 4. For Pascal: upgrade to version 1.9.2 or higher
  5. 5. For Pasconnect: upgrade to version 1.4.0 or higher
  6. 6. For Pasmotion: upgrade to version 1.4.1 or higher
  7. 7. For Pnozmulti Configurator: upgrade to version 10.14.4 or higher, or version 11.2.0 or higher
  8. 8. Verify the upgrade was successful by checking the new version number
