## Overview

Affected devices do not properly sanitize calculated signal data contained in imported CSV trace files before rendering it on the Trace page.

This could allow an attacker to social engineer an authorized user who holds the function right “Read diagnostics” into importing a specially crafted trace file. Successful exploitation could allow attacker-controlled JavaScript to execute in the user’s browser session and perform PLC operations through the web server within the scope of the user’s authorization.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
