Risk Evaluation

A stored cross-site scripting vulnerability has been discovered in the profinet gateway LB8122A.1.EL. An attacker can write an HTML tag with up to 32 characters in the message field of a HART transmitter. The HTML tag is interpreted as HTML when the HART information is displayed in a webbrowser. If the HTML tag contains a link to a manipulated page, a user can be tricked into accessing this page. Furthermore, an attacker can access information about running processes via the SNMP protocol. Sending such SNMP read commands can also trigger a reboot.

Zusammenfassung der Gegenmaßnahmen
