#Security Vulnerability

**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 gather information specific to the environment of the targeted component.

**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 gather information specific to the environment of the targeted component.

**How could an attacker exploit this vulnerability?** In most situations, an unauthenticated attacker could send a specially crafted packet to a targeted server utilizing the HTTP Protocol Stack (http.sys) to process packets.

**How could an attacker exploit this vulnerability?** To exploit this vulnerability, an unauthenticated attacker would need to send a specially crafted RPC call to an RPC host. This could result in remote code execution on the server side with the same permissions as the RPC service.

**How could an attacker exploit this vulnerability?** An authenticated attacker with normal privileges could send a modified XPS file to a shared printer, which can result in a remote code execution.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** The vulnerability is in the web client, but the malicious scripts executed in the victim’s browser translate into actions executed in the (remote) cluster.

**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.

**Why is the CERT/CC the assigning CNA (CVE Numbering Authority)?** This CVE is regarding a vulnerability in a third party driver. CERT/CC created this CVE on behalf of the researcher who discovered the vulnerability.

**How could an attacker exploit this vulnerability?** An authenticated attacker with normal privileges could send a modified XPS file to a shared printer, which can result in a remote code execution.

**Why is this GitHub CVE included in the Security Update Guide?** The vulnerability assigned to this CVE is in Git for Windows software which is consumed by Microsoft Visual Studio. It is being documented in the Security Update Guide to announce that the latest builds of Visual Studio are no longer vulnerable.
