CVE-2026-9852 High · 7.8 CWE-1236 Sep 3, 2026
CSV Injection in Hitachi Energy Microscada X Sys600
A CSV injection vulnerability exists in SYS600. Injected malicious formulas can add or modify data to the spreadsheet, insert links, exfiltrate data, and in some cases, depending on how the user has their environment configured, execute malicious code on the user’s machine. To exploit this issue attackers would need a way to create arbitrary log messages. This could be achieved through normal functionality via SCIL scripts, a log injection vulnerability, or via the SYS600 broker. This vulnerability affects all Windows users regardless of their privilege level who can run the Notify service and export the log.
CVE-2026-17539 Medium · 5.9 CWE-476 Sep 3, 2026
NULL Pointer Dereference in Hitachi Energy RTU500 series CMU firmware
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.
CVE-2026-10763 High · 7.0 Jun 30, 2026

PROMOD V is using insecure HTTP communication instead of HTTPS. The vulnerability is due to the lack of HTTPS support from 3rd party Digipede server.
CVE-2026-8479 Medium · 6.9 CWE-476 May 26, 2026
NULL Pointer Dereference in Hitachi Energy RTU500 series CMU firmware
IEC 60870-5-104 used in bidirectional mode in RTU500 is vulnerable for a NULL pointer dereferencing, if a specially crafted sequence of messages is sent for a certain time, causing Denial of Service impact. Product is only affected if IEC 60870-5-104 functionality in bidirectional mode (BCI) is configured.
CVE-2026-7310 Medium · 4.4 CWE-122 May 26, 2026
