#vulnerability

**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.

**According to the CVSS metric, the attack vector is physical (AV:P). What does that mean for this vulnerability?** To exploit this vulnerability, an unauthenticated attacker needs to physically connect a malicious USB device to the victim's machine.

**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.

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

Welcome to the third installment in our series on transparency at the Microsoft Security Response Center (MSRC). In this ongoing discussion, we talk about our commitment to providing comprehensive vulnerability information to our customers. At MSRC, our mission is to protect our customers, communities, and Microsoft, from current and emerging threats to security and privacy.
