CVE-2018-5706
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn issue was discovered in Octopus Deploy before 4.1.9. Any user with user editing permissions can modify teams to give themselves Administer System permissions even if they didn't have them, as demonstrated by use of the RoleEdit or TeamEdit permission.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIn Octopus Deploy before 4.1.9, a privilege escalation vulnerability exists where any user with user editing permissions (specifically RoleEdit or TeamEdit) can modify team assignments to grant themselves Administer System permissions they were not originally assigned, bypassing proper authorization checks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Octopus Deploy versionNavigate to the Octopus Deploy web UI (typically /about or /admin/configuration page) or check via server CLI if available. Identify the exact version number running.Affected if Version is earlier than 4.1.9
-
Identify users with RoleEdit or TeamEdit permissionsIn the Octopus Deploy web UI, go to Users and Teams configuration. Review which users or teams have RoleEdit or TeamEdit permissions specifically enabled.Affected if Any non-administrator user account has RoleEdit or TeamEdit permissions
-
Audit recent team membership changesReview Octopus Deploy audit logs or team history for modifications to team assignments, particularly teams that grant Administer System permissions.Affected if Recent team modifications exist that add users to Administer System teams without proper authorization
-
Verify Administer System permission assignmentsIn the Octopus Deploy UI, review which users and teams have the Administer System permission. Cross-reference with expected administrator accounts and authorized user list.Affected if Users who should not have administrative access have been granted Administer System permissions
Environment is affected if running Octopus Deploy version below 4.1.9 AND any user has RoleEdit or TeamEdit permissions that could be exploited to grant themselves unauthorized Administer System access.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor data4.1.9
Upgrade to Octopus Deploy 4.1.9 or later. Until then, restrict user editing permissions to only highly trusted administrators and monitor for unauthorized team modifications.
