A specially crafted series of network requests can lead to a denial of service. An attacker can send a sequence of unauthenticated packets to trigger this vulnerability.An attacker can trigger this denial-of-service condition by sending a single Modbus TCP message to port 503 using the Write Single Register function code (6) to write the value 1 to register 4352. This action changes the Modbus address to 15. After this message is sent, the device will be in a denial-of-service state.","publishedAt":"2025-12-01T15:25:13.358Z","updatedAt":"2025-12-01T20:17:51.595Z","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":"talos"},"assigner":"talos","products":["Socomec DIRIS Digiware M-70"],"affected":[{"vendor":"Socomec","product":"DIRIS Digiware M-70","versions":[{"version":"1.6.9","status":"affected"}]}],"references":["https://talosintelligence.com/vulnerability_reports/TALOS-2025-2248"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:09:31.862Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/54xxx/CVE-2025-54851.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-54851","state":"PUBLISHED","datePublished":"2025-12-01T15:25:13.358Z","dateUpdated":"2025-12-01T20:17:51.595Z","assignerShortName":"talos","assignerOrgId":"b86d76f8-0f8a-4a96-a78d-d8abfc7fc29b","dateReserved":"2025-07-31T15:17:58.546Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"A denial of service vulnerability exists in the Modbus TCP and Modbus RTU over TCP functionality of Socomec DIRIS Digiware M-70 1.6.9.
