Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-67041 is a critical vulnerability affecting Lantronix EDS3000PS version 3.1.0.0R2. The issue resides in the TFTP client functionality within the Filesystem Browser page, where the host parameter is not properly sanitized. This flaw enables an attacker to escape the intended command context and inject arbitrary operating system commands that execute with root privileges. The vulnerability is associated with CWE-78 (Improper Neutralization of Special Elements used in an OS Command), CWE-288 (Authentication Bypass Using an Alternate Path or Channel), and CWE-620 (Unverified Code), earning a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Remote attackers require no privileges, authentication, or user interaction to exploit this vulnerability over the network with low complexity. Successful exploitation grants full root-level remote code execution on the affected device, potentially allowing complete compromise including data exfiltration, persistence, lateral movement, or disruption of device operations.
Mitigation guidance is detailed in CISA ICS Advisory ICSA-26-069-02, as well as vendor resources at lantronix.com and eds3000ps.com. Security practitioners should consult these advisories for patching instructions, workarounds, and affected product details.

Mitigating Controls (NIST 800-53 r5) AI
Requires a tamperproof, always-invoked reference monitor that structurally blocks bypass via any alternate path.
Enforces authorization checks on every logical access path, eliminating unauthenticated alternate channels.
Re-authentication explicitly requires users to prove identity before performing sensitive actions such as password changes.
Mandates unique identification and authentication for all organizational users, covering the primary authentication requirement.
Authenticator management requires identity verification during password distribution and changes, directly stopping unverified password updates.
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Requiring authentication on every channel and path directly eliminates alternate-path bypasses.
Credential management practices directly enforce re-authentication for password changes.
Enforcing authorizations and least privilege across all access vectors prevents unauthenticated alternate paths.
Protecting networks and environments from unauthorized logical access blocks bypass via undocumented channels.
PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.
Secure authentication control directly mitigates bypass by requiring strong, consistent authentication on all paths.
Access control policy directly addresses alternate authentication paths by requiring all channels to enforce authentication.
Authentication information management ensures credentials and mechanisms are consistently applied across all access paths.
Access rights provisioning and review prevent bypass via unmonitored or alternate channels.
Privileged access rights control reduces risk of bypass through elevated or alternate paths.
