How to read security threats in the Threat Data Bank (UBI FSTEC)?

Question

Information Security

Here is an example of a threat from the FSTEC BDU:
UBI No. 8 : Threat to restore authentication information
The threat consists in the possibility of selecting (for example, by exhaustive enumeration or enumeration in a dictionary) the authentication information of a compromised user account in the system.
Source: Low potential external intruder Target
#1: System software
Target #2: Firmware
Target #3: User credentials
How to read it? I guess it should read something like this:

if the object of influence 1 is attacked in accordance with threat 1, then the following properties of the protected information will be violated: conf, integrity, availability

What will be the protected information in the case of each target: authentication information or protected data (letters, prices, etc.)?
