**According to the CVSS metrics, the attack vector is local (AV:L) and privilege required is low (PR:L). What does that mean for this vulnerability?** An attacker must have local access to the targeted machine and must be able to create folders and performance traces on the machine, with restricted privileges that normal users have by default.

**How could an attacker exploit this vulnerability?** A remote unauthenticated attacker could exploit this vulnerability by sending specially crafted requests to a vulnerable .NET webapp or by loading a specially crafted file into a vulnerable desktop app.

**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 network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** This attack requires a client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.

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

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

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

**How could an attacker exploit this vulnerability?** An attacker with basic user permissions can send specially crafted requests to modify the configuration of an Azure CycleCloud cluster to gain Root level permissions enabling them to execute commands on any Azure CycleCloud cluster in the current instance and in some scenarios, compromise administrator credentials.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** In this case, a successful attack could be performed from a low privilege Hyper-V guest. The attacker could traverse the guest's security boundary to execute code on the Hyper-V host execution environment.

**According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** This attack requires a client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.
