Severity: 4-Minor


The 'tmsh modify auth password' command appears to allow the password to be changed for the f5hubblelcdadmin user.


This operation appears to succeed, but has no actual effect on BIG-IP operations. This is an internal user account which provides the context for communication with the lcd front panel display on newer BIG-IP appliances. Changing the stored password for this user account does not affect these operations.


Using the 'modify auth password' command under tmsh, and manually specifying the 'f5hubblelcdadmin' user (which does not appear among the list of available users, such as via tab-completion).



Fix Information

Removed the appearance of the ability to change the password for the internal lcd admin user.
