| Title | Denial of Service via NULL Pointer Dereference in Hitachi Energy RTU500 IEC 60870-5-104 Communication |
| Type | Values Removed | Values Added |
|---|---|---|
| Description | RTU500 has a vulnerability, where high-load scenarios, such as sending GI requests at short intervals, may cause a NULL pointer dereference in the last entry of the enhanced message queue. This can cause a BCI_IEC104 fatal write error, resulting in connection interruption and restart, and ultimately a denial of service for bidirectional IEC 60870-5-104 communication. | |
