# UserInteraction

Describes whether a user, other than the attacker, is required to do anything or participate in exploitation of the vulnerability. User interaction has two possible values: None (N) – No user interaction is required, Required (R) – A user must complete some steps for the exploit to succeed. For example, a user might be required to install some software.
