Security readout for executives and security teams
Plain-English summary
Pilz PASvisu before 1.14.1 has a cross-site scripting flaw in its Builder Component. A local unauthenticated attacker could inject malicious JavaScript if a user interacts with affected content, potentially leading to full device control.
Executive priority
Treat as a high-priority industrial control exposure where affected systems are present. Prioritize version verification and vendor-guided updates before routine maintenance windows if devices support operational processes.
Technical view
CVE-2023-45795 is CWE-79 XSS in the Pilz PASvisu Builder Component, also tied to PMI v8xx exposure. CVSS 3.1 is 7.8, with local access, low complexity, no privileges, and user interaction required. Reported impacts are high for confidentiality, integrity, and availability.
Likely exposure
Organizations using Pilz PASvisu before 1.14.1, especially with PMI v8xx environments or locally accessible Builder Component workflows, should assume potential exposure until versions are verified.
Exploitation context
The source bundle does not indicate public exploitation or CISA KEV listing. Exploitation is described as local and unauthenticated, but requires user interaction.
Researcher notes
Evidence is limited to the CVE source bundle and CERT@VDE reference. The affected version entries include placeholder-style values, so use the vendor advisory and local asset data to confirm exact exposure.
Mitigation direction
- Upgrade PASvisu to version 1.14.1 or later where applicable.
- Review and follow the CERT@VDE vendor advisory.
- Restrict local access to PASvisu Builder Component systems.
- Limit engineering workstation access to trusted personnel only.
- Monitor affected devices for unexpected configuration or project changes.
Validation and detection
- Inventory all Pilz PASvisu and PMI v8xx deployments.
- Confirm PASvisu versions and identify any before 1.14.1.
- Verify whether the Builder Component is locally accessible.
- Check vendor advisory details against installed product versions.
- Review systems for suspicious script-like project content.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
