Mitigation checklist
- To mitigate this issue, avoid persistent SendTargets discovery when connecting to untrusted or interceptable networks. If persistent discovery is operationally necessary, ensure that node records created from untrusted discovery results are removed before any subsequent update or login operations. Alternatively, use nonpersistent discovery mode where feasible. Changes to iSCSI configuration may require restarting the `iscsid` service for the changes to take full effect, which could temporarily disrupt iSCSI connections.
