**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to prepare the target environment to improve exploit reliability.

**What privileges could be gained by an attacker who successfully exploited the vulnerability?** An attacker who successfully exploited this vulnerability could gain access to the credentials of other users on the system.

**According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires the attacker to be able to send a malicious update package to the Defender for IoT sensor over the network. To do this, the attacker would first need to authenticate themselves and gain the necessary permissions to initiate the update process.

**According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires the attacker to be an administrator of the web application. As is best practice, regular validation and audits of administrative groups should be conducted.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**According to the CVSS metric, the attack vector is Adjacent (AV:A), the attack complexity is high (AC:H) and the privileges required is high (PR:H). What does this mean for this vulnerability?** An authenticated attacker would need to have access to a proxy server created in the same or in an accessible network of the Appliance.

**What privileges could be gained by an attacker who successfully exploited this vulnerability?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** A user needs to be tricked into running malicious files.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to take additional actions prior to exploitation to prepare the target environment.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could bypass Secure Boot.
