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.","publishedAt":"2023-07-26T05:25:27.002Z","updatedAt":"2025-03-05T18:47:06.707Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","source":"Hitachi Energy"},"assigner":"Hitachi Energy","products":["Hitachi Energy RTU500 series"],"affected":[{"vendor":"Hitachi Energy","product":"RTU500 series","defaultStatus":"unaffected","versions":[{"version":"RTU500 series CMU Firmware version 13.3.1","status":"affected"},{"version":"RTU500 series CMU Firmware version 13.3.2","status":"affected"},{"version":"RTU500 series CMU Firmware version 13.3.3","status":"unaffected"},{"version":"RTU500 series CMU Firmware version 13.4.1","status":"unaffected"}]}],"references":["https://publisher.hitachienergy.com/preview?DocumentID=8DBD000121&LanguageCode=en&DocumentPartId=&Action=Launch","https://search.abb.com/library/Download.aspx?DocumentID=8DBD000121&LanguageCode=en&DocumentPartId=&Action=Launch"],"weaknesses":["CWE-20"],"ingestedAt":"2026-10-29T19:50:01.354Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/2xxx/CVE-2022-2502.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-2502","state":"PUBLISHED","datePublished":"2023-07-26T05:25:27.002Z","dateUpdated":"2025-03-05T18:47:06.707Z","assignerShortName":"Hitachi Energy","assignerOrgId":"e383dce4-0c27-4495-91c4-0db157728d17","dateReserved":"2022-07-21T06:25:31.199Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"A vulnerability exists in the HCI IEC 60870-5-104 function included in certain versions of the RTU500 series product.
