#Azure DevOps

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.

**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.

**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,privileges required is low(PR:L). What does that mean for this vulnerability?** This means that an attacker needs to have a user account in the organization with the ability to run builds.

**How could an attacker exploit this vulnerability?** An attacker could exploit an integer overflow vulnerability that results in arbitrary heap writes, which could be used to perform arbitrary code execution.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to minor loss of confidentiality (C:L), integrity (I:L) and availability (A:L). What does that mean for this vulnerability?** While we cannot rule out the impact to Confidentiality, Integrity, and Availability, the ability to exploit this vulnerability by itself is limited. An attacker would need to combine this with other vulnerabilities to perform an attack.

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

**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.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker would have to send the victim a malicious link that the victim would have to click for a successful attack.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** An attacker would have to send the victim a malicious link that the victim would have to click for a successful attack.
