Privileges required is a metric in the Common Vulnerability Scoring System (CVSS) that measures the level of access needed to launch a successful attack. The higher the privileges required, the lower the severity of the vulnerability. The privileges required metric has three possible values: none, low, and high. None means that the attacker does not need any privileges to exploit the vulnerability. Low means that the attacker needs privileges that provide basic user capabilities. High means that the attacker needs privileges that provide significant or administrative control over the target. References: Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 2-17; 200-201 CBROPS - Cisco, exam topic 1.3.c
