CVE-2016-1984

Status: ModifiedCritical (9.8)—

The setUpSubtleUserAccount function in /bin/bw on Harman AMX devices before 2016-01-20 has a hardcoded password for the 1MB@tMaN account, which makes it easier for remote attackers to obtain access via a (1) SSH or (2) HTTP session, a different vulnerability than CVE-2015-8362.
