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 stored cross-site scripting vulnerability in the Runtime component of Pilz PASvisu before 1.14.1 and PMI v8xx up to and including 2.0.33992 allows a low-privileged remote unauthenticated attacker to manipulate process data with potential impact on integrity and/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

Stored cross-site scripting (XSS) vulnerability in the Runtime component of Pilz PASvisu (visualization software) and PMI v8xx (industrial operator panels). A low-privileged remote unauthenticated attacker can inject malicious scripts into process data that gets stored and executed when viewed by other users, allowing manipulation of process data impacting integrity and availability.

MitigationUpdate PASvisu to version 1.14.1 or later, and update PMI v8xx to a version beyond 2.0.33992. Additionally, implement proper input validation, output encoding, and consider network segmentation to limit exposure.

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 visualization product
    Locate PASvisu or PMI v8xx software on the system by checking installed programs, program files directories, or documentation. Look for Pilz PASvisu or PMI v8xx in the system inventory or registry.
    Affected if Either PASvisu or PMI v8xx is installed and the version is below 1.14.1 for PASvisu or 2.0.33992 for PMI v8xx
  2. Determine PASvisu version
    Check the installed version of PASvisu through the software's about dialog, installation directory, or system registry. Compare the found version to 1.14.1.
    Affected if Version is present and is below 1.14.1
  3. Determine PMI v8xx firmware version
    Check the firmware version of the PMI v8xx operator panel through its web interface, system information menu, or documentation. Compare the found version to 2.0.33992.
    Affected if Firmware version is present and is 2.0.33992 or earlier
  4. Verify Runtime component exposure
    Check if the PASvisu Runtime web interface or service is accessible from the network. Look for open ports (typically 80/443 for web-based Runtime) and verify if authentication is required for access.
    Affected if The Runtime component is network-accessible without requiring authentication or uses weak authentication controls
  5. Check for unauthenticated process data access
    Examine whether the Runtime allows unauthenticated or low-privileged users to write process data that gets displayed to other users. Review user role configurations and access control settings.
    Affected if Unauthenticated or low-privileged users can inject data that gets stored and displayed to other users without sanitization

You are affected if either PASvisu below version 1.14.1 or PMI v8xx at firmware 2.0.33992 or earlier is installed, and the Runtime component is accessible allowing unauthenticated or low-privileged users to inject stored script content into process data.

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

Update PASvisu to version 1.14.1 or later, and update PMI v8xx to a version beyond 2.0.33992. Additionally, implement proper input validation, output encoding, and consider network segmentation to limit exposure.
