A vulnerability exists in the RTU500 web server component that can cause a denial of service to the RTU500 CMU application if a specially crafted message sequence is executed on a WebSocket connection. An attacker must be properly authenticated and the test mode function of RTU500 must be enabled to exploit this vulnerability.
The affected CMU will automatically recover itself if an attacker successfully exploits this vulnerability.
A vulnerability exists in the IEC 61850 communication stack that affects multiple Hitachi Energy products.
An attacker could exploit the vulnerability by using a specially crafted message sequence, to force the IEC 61850 MMS-server communication stack, to stop accepting new MMS-client connections.
Already existing/established client-server connections are not affected.

A vulnerability exists in the HCI IEC 60870-5-104 function included in certain versions of the RTU500 series product. The vulnerability can only be exploited, if the HCI 60870-5-104 is configured with support for IEC 62351-5 and the CMU contains the license feature ‘Advanced security’ which must be ordered separately. If these preconditions are fulfilled, an attacker could exploit the vulnerability by sending a specially crafted message to the RTU500, causing the targeted RTU500 CMU to reboot. The vulnerability is caused by a missing input data validation which eventually if exploited causes an internal buffer to overflow in the HCI IEC 60870-5-104 function.
A vulnerability exists in HCI IEC 60870-5-104 function included in certain versions of the RTU500 series product. The vulnerability can only be exploited, if the HCI 60870-5-104 is configured with support for IEC 62351-3. After session resumption interval is expired an RTU500 initiated update of session parameters causes an unexpected restart due to a stack overflow.
Vulnerability exists in SCI IEC 60870-5-104 and HCI IEC 60870-5-104 that affects the RTU500 series product versions listed below. Specially crafted messages sent to the mentioned components are not validated properly and can result in buffer overflow and as final consequence to a reboot of an RTU500 CMU.
A vulnerability exists in the HCI Modbus TCP function included in the product versions listed above. If the HCI Modbus TCP is en-abled and configured, an attacker could exploit the vulnerability by sending a specially crafted message to the RTU500, causing the receiving RTU500 CMU to reboot. The vulnerability is caused by the validation error in the length information carried in MBAP header in the HCI Modbus TCP function.
Improper Input Validation vulnerability in the APDU parser in the Bidirectional Communication Interface (BCI) IEC 60870-5-104 function of Hitachi Energy RTU500 series allows an attacker to cause the receiving RTU500 CMU of which the BCI is enabled to reboot when receiving a specially crafted message. By default, BCI IEC 60870-5-104 function is disabled (not configured). This issue affects: Hitachi Energy RTU500 series CMU Firmware version 12.0. (all versions); CMU Firmware version 12.2. (all versions); CMU Firmware version 12.4. (all versions).
