Summary:

Integrated Data Protection Appliance (iDPA) contains undocumented
accounts with limited access which may potentially be

used by a malicious user to compromise the affected system.



Details:

Integrated Data Protection Appliance versions 2.0, 2.1, and 2.2 contain
undocumented accounts named "support" and
"admin" that are protected with default passwords. These accounts have
limited privileges and can access certain system
files only. A malicious user with the knowledge of the default passwords
may potentially log in to the system and gain
read and write access to certain system files.



Resolution:

Follow the steps below to remove the user accounts named "support" and
"admin" from the impacted virtual machines in
the Integrated Data Protection Appliance. There is no loss of
supportability or any other product functionality as a
result of the removal of these accounts.



Log in to Data Protection Advisor - Datastore Server Virtual Machine
using an SSH client such as PuTTY, as root user and execute the
following commands:



Delete the user "support"

userdel support



Delete the user "admin"

userdel admin



Verify that the accounts are deleted. The following commands should
display "no such user" as the output.

id support

id admin

procedure for Data Protection Advisor -
Application server, Data Protection Advisor - Agent, Data Protection
Advisor - DD Data Processor Tool and Appliance Configuration Manager
