Affected devices do not properly validate and sanitize Technology Object (TO) name rendered on the "Motion Control Diagnostics" 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 "Motion Control Diagnostics" parameters page, the malicious code would be executed in the scope of their web session.
