While no EPSS data is available, the lack of authentication suggests a straightforward remote exploitation path from any network segment that can reach the device\u2019s management interface.

Nonetheless, attackers could leverage standard network tools to modify configurations if they gain network access to the management interface."}}}}, "created": "2026-04-20T05:30:44.130308+00:00", "title": "Missing Authentication Allows Device Configuration Changes", "updated": "2026-04-20T05:30:44.130318+00:00", "vendors": []}
