Official Description
Network Appliance Data ONTAP 7.0 and earlier allows iSCSI Initiators to bypass iSCSI authentication via a modified client that skips the Security (Start) mode, as required by the Login Negotiation protocol, and uses Operational mode without proving identity.
Technical Analysis
CVE-2005-3327 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
