Remote API call (AV:N) at low complexity (AC:L) requires an authenticated non-admin with delegated enrollment permission (PR:L) and no user interaction; redeeming the token yields full admin, so C/I/A:H.

8DescriptionCVE.org
OpenZiti through 2.0.0, fixed in commit 3027fdf, contains a privilege escalation vulnerability that allows authenticated non-admin identities with fine-grained enrollment management permissions to create enrollments for any identity, including the default administrator, because the ApplyCreate function in controller/model/enrollment_manager.go verifies only that the target identity exists without performing authorization checks binding the caller to the target identity. Attackers can redeem the resulting one-time token through the unauthenticated client API enrollment endpoint to obtain a client certificate authenticating as the targeted admin identity, yielding full administrative control of the controller and the zero-trust overlay it manages.
AnalysisAI
Privilege escalation in OpenZiti through 2.0.0 lets an authenticated non-admin identity that holds fine-grained enrollment-management permissions mint an enrollment for any identity - including the built-in default administrator - and then redeem the resulting one-time token via the unauthenticated client enrollment API to receive a client certificate that authenticates as that admin, granting full control of the controller and the entire zero-trust overlay. The root cause is a missing authorization check (CWE-862) in the enrollment creation path. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must already possess a valid, authenticated non-admin OpenZiti identity that has been granted fine-grained enrollment-management (entity-level enrollment create) permissions - this delegated permission is the exact prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All decision signals point to a genuine, high-priority issue rather than a high-CVSS paper risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who controls a low-privileged OpenZiti identity that has been delegated enrollment-management permissions calls the controller's create-enrollment API specifying the default administrator's identity as the target; because no authorization check binds caller to target, the controller mints a one-time enrollment token for the admin. The attacker then redeems that token through the unauthenticated client API enrollment endpoint, obtains a client certificate authenticating as the admin, and gains full administrative control of the controller and overlay. … |
| Remediation | Upgrade OpenZiti to the build containing the fix in commit 3027fdffd3e57884487b7c46e5e669cfbc8becdf (merged via pull request https://github.com/openziti/ziti/pull/4013); an upstream fix is available but the specific tagged released version was not provided, so confirm the exact patched release with the vendor before deploying. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
24 hours: Identify all OpenZiti deployments and audit which users or service accounts hold enrollment-management permissions; assess exposure if untrusted or high-risk personnel possess these permissions. …
