Jenkins Azure VM Agents Plugin 852.v8d35f0960a_43 and earlier does not perform permission checks in several HTTP endpoints.
This allows attackers with Overall/Read permission to connect to an attacker-specified Azure Cloud server using attacker-specified credentials IDs obtained through another method.
Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-site request forgery (CSRF) vulnerability.
Azure VM Agents Plugin 853.v4a1add947520 requires POST requests and the appropriate permissions for the affected HTTP endpoints.
