CVE-2024-28812

Highest-privilege OS access via hardcoded SSH credentials

Published Sep 30, 2024 · Updated Sep 30, 2024

Hardcoded credentials in Infinera hiT 7300 5.60.50 allow remote attackers to gain highest-privilege OS access via the management network. A hidden SSH service on the local management interface accepts embedded credentials and opens an operating-system shell with the highest privileges. Reachability requires adjacent access to the local management network; successful authentication grants full control of the appliance operating system.
