Summary

CVE-2025-67037 is a high-severity Code Injection (CWE-94) vulnerability in Lantronix Eds5032 Firmware. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 30.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).

Deeper analysis

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.
