CVE-2025-67039Network attack vector

Unauthenticated management access via crafted URL and header

Published Mar 11, 2026 · Updated Mar 11, 2026

Authentication bypass in Lantronix EDS3000PS 3.1.0.0R2 allows remote attackers to access management pages without credentials. The web management handler accepts a specific URL suffix and an Authorization header naming the admin user without validating corresponding credentials. Network access to the management interface is sufficient; exposed administrative functions permit reading and changing device configuration, while service interruption is not reported.
