Questiоn Set 3 - 3.2 Cоmmоn Vulnerаbility Scoring System (CVSS) is а common аpproach to measuring the severity of a vulnerability. It is an open framework for communicating the characteristics and impacts of IT vulnerabilities and it consists of three metric groups (a) Base metric: constant over time and with user environment. (b) Temporal metric: change over time but constant with user environment. (c) Environmental metric: unique to the user environment. Among these metrics, the base metric is widely used. For example, ShellShock vulnerability (CVE-2014-6271)’s base metric (or score) is 10. Attackers target the Apache HTTPD Server running dynamic content CGI modules to allow remote attackers to execute arbitrary code via craft environment variables. Referring to Tables 3.1 and 3.2 above, which of the following descriptions correctly describes the severity of the ShellShock vulnerability? (select all that apply) Its base metrics are summarized in Table 3.1and Table 3.2 below: Table 3.1 - CVSS Metrics for Web Server Bash Shell Interpreter Vulnerability CVSS Metric Value Comment Attack Vector Network Web Server Attack Access Complexity Low Attacker needs to access service using bash shell interpreter. Privileges None CGI in web server requires no privilege. User Interaction None No user interaction required to launch successful attack. Scope Unchanged GNU bash shell is vulnerable compenent, which can be used without any change in the scope. Table 3.2 - CVSS Impact Assessment for Bash Shell Interpreter Vulnerability CVSS Metric Value Comment Confidentiality Impact (C) High Attacker can take complete command and control (C&C) of the affected system. Integrity Impact (I) High Attacker can take complete command and control (C&C) of the affected system. Availability Impact (A) High Attacker can take complete command and control (C&C) of the affected system.
