Injected commands are executed with root privileges.","provenance":"source","from":"NVD"},"summary":{"text":"The Lantronix EDS5000 device, specifically firmware 2.1.0.0R3, contains a code injection flaw in its HTTP RPC module, which runs a shell command to write logs when authentication fails and concatenates the username into that command without sanitization. An attacker with network access can exploit this without authenticating or any user interaction by supplying crafted OS commands in the username parameter, which then execute with root privileges.","provenance":"ai","model":"claude-haiku-5-5","generatedAt":"2026-10-29T08:32:09Z"},"cvss":{"score":9.8,"severity":"CRITICAL","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","provenance":"source","from":"NVD"},"epss":{"score":0.20286,"percentile":0.97467,"date":"2026-10-29","provenance":"source"},"kev":{"dateAdded":"2026-06-23","dueDate":"2026-06-26","ransomware":false,"requiredAction":"Apply mitigations in accordance with vendor instructions, ensuring compliance with CISA’s BOD 26-04 Prioritizing Security Updates Based on Risk (see URL in Notes) guidance and CISA’s “Forensics Triage Requirements” (see URL in Notes).
