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 sequence of Modbus RTU over TCP messages to port 503 using the Write Single Register function code (6). The attack sequence begins with a message to register 58112 with a value of 1000, indicating that a configuration change will follow. Next, a message is sent to register 29440 with a value corresponding to the new Modbus address to be configured. Finally, a message to register 57856 with a value of 161 commits the configuration change.\r\nAfter this configuration change, the device will be in a denial-of-service state.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-306"],"references":["https://talosintelligence.com/vulnerability_reports/TALOS-2025-2248"],"products":["socomec:diris_m-70_firmware"],"source":"nvd","synced_at":"2026-10-19T22:16:02.354564667+00:00"},"epss":{"cve":"CVE-2025-54850","score":0.00321,"percentile":0.25186,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
