Summary

CVE-2025-67035 is a critical-severity Code Injection (CWE-94) vulnerability in Lantronix Eds5032 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 SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2025-67035 involves multiple OS command injection vulnerabilities (CWE-94) in Lantronix EDS5000 version 2.1.0.0R3. These flaws affect the SSH Client and SSH Server web pages, stemming from inadequate sanitization of input parameters. Attackers can inject arbitrary commands during delete actions for objects like server keys, users, and known hosts, with the commands executing under root privileges. The vulnerability carries 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), marking it as critical.

A remote, unauthenticated attacker can exploit this over the network with low attack complexity and no user interaction required. Exploitation allows execution of arbitrary root-level commands, enabling full system compromise, data exfiltration, modification of configurations, or disruption of device operations.

Advisories and patch information are detailed in CISA ICSA-26-069-02, along with resources on lantronix.com and eds5000.com. Security practitioners should review these for vendor-recommended mitigations, such as applying updates or implementing access controls.

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.

PR.PS-06 mostly match
prevents

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 none match
prevents

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.

prevents

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.

none

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.
