Brocade Fabric OS before Brocade Fabric OS v8.2.1c, v8.1.2h, and all versions of Brocade Fabric OS v8.0.x and v7.x contain documented hard-coded credentials, which could allow attackers to gain access to the system.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.35%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
