Microsoft Security Response Center

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of this vulnerability requires that an attacker convinces a user to open a maliciously crafted package file in Visual Studio.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**What kind of security feature could be bypassed by successfully exploiting this vulnerability?** An attacker who successfully exploited this vulnerability could bypass the Windows Defender Attack Surface Reduction blocking feature.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted URL to be compromised by the attacker.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is file content.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** Exploitation of the vulnerability requires that a user open a specially crafted file. * In an email attack scenario, an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. * In a web-based attack scenario, an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead, an attacker would have to convince users to click a link, typically by way of an enticement in an email or instant message, and then convince them to open the specially crafted file.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker must send the user a malicious file and convince them to open it.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** The user would have to click on a specially crafted URL to be compromised by the attacker.

**According to the CVSS metric, the attack vector is network (AV:N), attack complexity is low (AC:L), and privilege required is low (PR:L). What is the target used in the context of the remote code execution?** Successful exploitation of this vulnerability requires an attacker to have Queue Build permissions on an Azure DevOps pipeline that has an overridable variable. An attacker with these permissions could perform remote code execution (RCE) by performing a malicious input injection via a runtime parameter that could be used in place of the overridable variable.

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