The Quantum Scalar i500 tape library with firmware before i7.0.3 (604G.GS00100), also distributed as the Dell ML6000 tape library with firmware before A20-00 (590G.GS00100) and the IBM TS3310 tape library with firmware before R6C (606G.GS001), uses default passwords for unspecified user accounts, which makes it easier for remote attackers to obtain access via unknown vectors.
