Network devices must provide a logoff capability for administrator-initiated communication sessions.

If an administrator cannot explicitly end a device management session, the session may remain open and be exploited by an attacker; this is referred to as a zombie session.

Review the HP FlexFabric Switch configuration to determine if it provides a logoff capability for administrator-initiated communication sessions.

[HP] display users

Idx Line Idle Time Pid Type + 177 VTY 0 00:00:00 May 29 15:45:11 1011 SSH

Following are more details. VTY 0 : User name: admin@system Location: 16.117.204.17 + : Current operation user. F : Current operation user works in async mode.

If the HP FlexFabric Switch does not provide a logoff capability for these sessions, this is a finding.

Configure the HP FlexFabric Switch to provide a logoff capability for administrator-initiated communication sessions.
