CVE-2026-3867Network attack vector

Administrative hash disclosure via exported configuration ownership

Published Apr 27, 2026 · Updated Apr 27, 2026

Improper ownership management in Moxa EDR-8010 and EDR-G9010 routers allows remote authenticated users to read an administrator password hash. An exported configuration file retains ownership or access controls that permit a low-privileged account to retrieve the administrative account's hashed password. Exploitation requires prior configuration export, and the reported consequence is limited to disclosure from the affected router.
