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 502 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."}], "lastModified": "2025-12-08T19:23:54.010", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:socomec:diris_digiware_m-70_firmware:1.6.9:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "741E83B6-F217-46E7-9E3A-8E446250C785"}], "operator": "OR"}, {"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:h:socomec:diris_digiware_m-70:-:*:*:*:*:*:*:*", "vulnerable": false, "matchCriteriaId": "76CAA8C6-29FD-40F3-9702-790CD73F3052"}], "operator": "OR"}], "operator": "AND"}], "sourceIdentifier": "talos-cna@cisco.com"}
