CVE-2024-29966Network attack vector

Unauthenticated root access via documented default password

Published Apr 19, 2024 · Updated Aug 2, 2024

Hard-coded credentials for the Linux root account in Brocade SANnav before 2.3.0a allow remote attackers to access the appliance. The OVA installation guide publishes the account's default password, and affected installations do not force administrators to replace it. Exploitation requires that password to remain unchanged after installation and grants remote root access to the appliance.
