Description
Affected devices do not properly validate and sanitize PLC/station name rendered on the "communication" parameters page of the web interface.
This could allow an authenticated attacker who is authorized to download a TIA project into the product, to inject malicious scripts into the page.
If a benign user with appropriate rights accesses the "communication" parameters page, the malicious code would be executed in the scope of their web session.
