Detailsinfo

A vulnerability was found in gravitl netmaker up to 1.4.x. It has been classified as critical. This affects an unknown code block of the component Endpoint. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Netmaker makes networks with WireGuard. Prior to version 1.5.0, the Authorize middleware in Netmaker incorrectly validates host JWT tokens. When a route permits host authentication (hostAllowed=true), a valid host token bypasses all subsequent authorization checks without verifying that the host is authorized to access the specific requested resource. Any entity possessing knowledge of object identifiers (node IDs, host IDs) can craft a request with an arbitrary valid host token to access, modify, or delete resources belonging to other hosts. Affected endpoints include node info retrieval, host deletion, MQTT signal transmission, fallback host updates, and failover operations. This issue has been patched in version 1.5.0.
