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.","severity":{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.00645,"percentile":0.51204,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-120","CWE-20"],"published":"2023-07-26T05:25:27Z","modified":"2026-06-17T04:42:00Z","products":[{"vendor":"hitachi energy","product":"rtu500 series"},{"vendor":"hitachienergy","product":"rtu500_firmware"}],"references":[{"url":"https://publisher.hitachienergy.com/preview?DocumentID=8DBD000121\u0026LanguageCode=en\u0026DocumentPartId=\u0026Action=Launch","tags":["vendor-advisory"]},{"url":"https://search.abb.com/library/Download.aspx?DocumentID=8DBD000121\u0026LanguageCode=en\u0026DocumentPartId=\u0026Action=Launch","tags":["x_transferred"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-2502"},{"url":"https://github.com/advisories/GHSA-45rh-q5fv-wf42"}],"sources":{"cve":[{"id":"CVE-2022-2502","description":"A vulnerability exists in the HCI IEC 60870-5-104 function included in certain versions of the RTU500 series product.
