CVE-2020-28400 has a severity of medium, as it allows unauthenticated attackers to trigger a denial of service condition.
To fix CVE-2020-28400, update the affected devices to the latest firmware versions as specified by Siemens.
CVE-2020-28400 affects various Siemens products including SIMATIC PROFINET Driver Firmware versions up to 2.3 and several SCALANCE device versions below 5.2.5.
CVE-2020-28400 can be exploited by sending a large volume of DCP reset packets to interrupt service on the affected devices.
Currently, there is no specific workaround for CVE-2020-28400; updating to the fixed firmware is the recommended course of action.
