Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2017-17665 impacting octopus octopus_deploy. Evaluated with CVSS Base Score of 8.8 (HIGH).

Original NVD Description

Source: NIST NVD
In Octopus Deploy before 4.1.3, the machine update process doesn't check that the user has access to all environments. This allows an access-control bypass because the set of environments to which a machine is scoped may include environments in which the user lacks access.
