CVE-2023-33136: Azure DevOps Server Remote Code Execution Vulnerability

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.
