Summary

CVE-2025-67034 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 38.2th 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-2025-67034 is a command injection vulnerability (CWE-94) discovered in Lantronix EDS5000 version 2.1.0.0R3, published on 2026-03-11. The issue resides in the management interface, where an authenticated attacker can inject arbitrary OS commands into the "name" parameter during the deletion of SSL credentials. These injected commands execute with root privileges, earning 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 requires only low privileges (PR:L) to exploit this vulnerability remotely over the network (AV:N) with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation grants root-level command execution on the device, enabling full compromise including data exfiltration, modification of configurations, or further persistence.

Advisories providing mitigation guidance, including potential patches or workarounds, are detailed in CISA ICSA-26-069-02 (https://www.cisa.gov/news-events/ics-advisories/icsa-26-069-02) and on vendor sites such as http://eds5000.com and http://lantronix.com.
