Summary

CVE-2025-67041 is a critical-severity OS Command Injection (CWE-78) vulnerability in Lantronix Eds3016Ps1Ns Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 26th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-25 (Reference Monitor) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

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.

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).

finds

Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.

degrades

Secure authentication control directly mitigates bypass by requiring strong, consistent authentication on all paths.

prevents

Access control policy directly addresses alternate authentication paths by requiring all channels to enforce authentication.

degrades

Authentication information management ensures credentials and mechanisms are consistently applied across all access paths.

prevents

Access rights provisioning and review prevent bypass via unmonitored or alternate channels.

prevents

Privileged access rights control reduces risk of bypass through elevated or alternate paths.
