According to the CVSS metric, the attack vector is network (AV:N), attack complexity is high (AC:H), 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 the attacker to have Queue Build permissions and for the target Azure DevOps pipeline to meet certain conditions for an attacker to exploit this vulnerability.

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 server, but the malicious scripts execute in the victim’s browser on their machine.

According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?

Any authenticated attacker could trigger this vulnerability. It does not require admin or other elevated privileges.

According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?

The user would have to navigate to a page with malicious content to be compromised by the attacker.

According to the CVSS metric, successful exploitation of this vulnerability could lead to some loss of integrity (I:L)? What does that mean for this vulnerability?

The attacker is only able to modify the content of the vulnerable link to redirect the victim to a malicious site.

According to the CVSS metric, user interaction is required (UI:R) and privileges required is Low (PR:L). What does that mean for this vulnerability?

A non-admin local user who has sufficient permissions to create symbolic links on a Windows computer that has Azure Connected Machine Agent installed (or before the agent is installed) could create links from a directory used by the agent to other privileged files on the computer. If the administrator later installs virtual machine extensions on the machine, those files could be deleted.

What privileges could an attacker gain with successful exploitation?

An attacker who successfully exploited the vulnerability could add symlinks and cause an arbitrary file delete as SYSTEM.

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?

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.

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.

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?

An authenticated victim who is connected to the network must be tricked or persuaded to connect to a malicious SQL database using their SQL client application. After the connection is made, the server can send specially crafted replies to the client that exploit the vulnerability and permit execution of arbitrary code within the context of the user's SQL client application.

How could an attacker exploit this vulnerability?

An attacker would need to set up a malicious server and create a proof-of-concept script. The victim would then need to be convinced, possibly through social engineering techniques, to run this script, which would connect to the malicious server and potentially allow for remote code execution on the victim’s machine.

How could an attacker exploit this vulnerability?

An attacker could exploit the vulnerability by tricking an authenticated user into attempting to connect to a malicious SQL server via OLEDB, which could result in the server receiving a malicious networking packet. This could allow the attacker to execute code remotely on the client.

What is the relationship between Mark of the Web and Windows SmartScreen?

When you download a file from the internet, Windows adds the zone identifier or Mark of the Web as an NTFS stream to the file. So, when you run the file, Windows SmartScreen checks if there is a zone identifier Alternate Data Stream (ADS) attached to the file. If the ADS indicates ZoneId=3 which means that the file was downloaded from the internet, the SmartScreen does a reputation check. For more information on SmartScreen, please visit Microsoft Defender SmartScreen overview | Microsoft Learn.

According to the CVSS metric, user interaction is required (UI:R) and privileges required  is low (PR:L). What does that mean for this vulnerability?

An authorized attacker must send the user a malicious file and convince the user to open it.

What kind of security feature could be bypassed by successfully exploiting this vulnerability?

An attacker who successfully exploited this vulnerability could bypass the SmartScreen user experience.

According to the CVSS metric, successful exploitation of this vulnerability could lead to some loss of confidentiality (C:L), a total loss of integrity (I:H), and some loss of availability (A:L). What does that mean for this vulnerability?

The vulnerability allows a malicious actor to inject code into SmartScreen and potentially gain code execution, which could potentially lead to some data exposure, lack of system availability, or both.

According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?

An attacker could exploit the vulnerability by tricking an authenticated user (CVSS metric UI:R) into attempting to connect to a malicious SQL server via a connection driver (for example: ODBC and / or OLEDB as applicable).

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.

According to the CVSS score, the attack vector is adjacent (AV:A). What does this mean for this vulnerability?

This attack is limited to systems connected to the same network segment as the attacker. The attack cannot be performed across multiple networks (for example, a WAN) and would be limited to systems on the same network switch or virtual network.
