CVE-2025-67037 is a command injection vulnerability (CWE-94) in Lantronix EDS5000 version 2.1.0.0R3, published on 2026-03-11. The flaw occurs when an authenticated attacker injects operating system commands into the "tunnel" parameter during the process of killing a tunnel connection. These injected commands execute with root privileges on the affected device.
The vulnerability requires network access and low-privileged authentication (PR:L) with low attack complexity (AC:L) and no user interaction (UI:N), carrying a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). An attacker can exploit it remotely by authenticating to the EDS5000, then crafting a malicious "tunnel" parameter in a tunnel-kill request to execute arbitrary root-level commands, achieving high confidentiality, integrity, and availability impacts such as full device compromise.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation finds code paths that accept and execute externally influenced strings.
Input validation directly stops untrusted data from being used to construct executable code without neutralization.
Least privilege limits the damage an injected code fragment can perform once executed.
Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

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.
PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).
PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

Banning unapproved code samples and unauthenticated web services, combined with secure-coding standards and SAST, prevents the dynamic generation or inclusion of attacker-supplied code.
Controls that restrict unauthorized or malicious code from being introduced via external networks or removable media limit opportunities for an attacker to inject and execute arbitrary code.
