CVE-2023-45796: XSS vulnerability in Pilz PASvisu and PMI v8xx

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.

Security readout for executives and security teams

Plain-English summary

Pilz industrial visualization software may let a low-privileged remote attacker store malicious script content that manipulates process data. The reported impact is not data theft, but integrity and availability: incorrect or disrupted process information could affect operations.

Executive priority

Treat this as a high-priority OT integrity and availability risk. Prioritize exposed or production-critical Pilz visualization systems first, then apply vendor guidance and network restrictions through normal change controls.

Technical view

CVE-2023-45796 is a stored XSS issue in the Runtime component of Pilz PASvisu before 1.14.1 and PMI v8xx up to 2.0.33992. It is CWE-79 with CVSS 3.1 score 8.1: network attack, low complexity, low privileges, no user interaction, high integrity and availability impact.

Likely exposure

Exposure is most likely in industrial environments using Pilz PASvisu or PMI v8xx Runtime interfaces, especially where those interfaces are reachable beyond tightly controlled OT networks. Confirm product and version from asset inventory, because the source bundle does not provide deployment prevalence.

Exploitation context

The provided bundle does not show CISA KEV listing or confirmed active exploitation. The vulnerability is serious because stored XSS in an HMI/runtime context can persist and affect process data integrity or availability without requiring user interaction per the CVSS vector.

Researcher notes

The source wording says both low-privileged and unauthenticated, while the CVSS vector uses PR:L. Treat privilege requirements as low privileges unless vendor clarification says otherwise. No exploit details, public exploitation, or complete PMI remediation version are provided in the bundle.

Mitigation direction

  • Upgrade PASvisu to 1.14.1 or later where applicable.
  • Check Pilz/CERT@VDE guidance for PMI v8xx fixed versions or workarounds.
  • Restrict Runtime and HMI interfaces to trusted OT management networks.
  • Review low-privileged accounts and remove unnecessary access.
  • Monitor process data integrity and abnormal Runtime behavior.

Validation and detection

  • Inventory PASvisu and PMI v8xx assets and record Runtime versions.
  • Flag PASvisu versions before 1.14.1 as affected.
  • Flag PMI v8xx versions up to 2.0.33992 as affected.
  • Verify Runtime interfaces are not internet-exposed.
  • Check logs for unexpected process data changes or script-like stored content.
