Short explanation

A cross-site scripting vulnerability exists in Siemens SIMATIC Drive Controller CPU 1504D TF and related devices due to improper sanitization of calculated signal names in imported CSV trace files.

Why does it matter?

This flaw can allow attacker-controlled JavaScript code to be executed within an authorized user's browser session, facilitating potential compromise.

What should be done?

  • Follow vendor advisories and apply updates
  • Avoid importing CSV files from untrusted sources
Note on uncertainty

The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.

Show the technical text from the sources

Affected devices do not properly sanitize calculated signal names contained in imported CSV trace files before including them in error messages 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. Attacker-controlled JavaScript could be executed in the user’s browser session when the resulting error message is displayed.
