Account compromise via unlimited login attempts
Published Sep 11, 2026 · Updated Sep 11, 2026
Missing brute-force protection in Kingdom Communication Associated EH-series intercoms allows remote attackers to compromise valid accounts. The login authentication interface accepts a large number of successive attempts without documented throttling or account lockout. No authentication is needed to submit the attempts; a successful guess grants access only to the compromised account, with no broader impact reported.
