Summary

Nginx UI from 2.0.0 before 2.5.0 is affected. Its /api/nodes endpoints serialize each node token, so an authenticated user with ordinary privileges can read tokens (CWE-200). The token is accepted as node authentication and maps the request to the initUser account, so the user can impersonate a trusted cluster node and reach its sensitive management operations, such as configuration synchronization and service restart. The references link a public exploit.

Description from the CNA

Nginx UI is a web user interface for the Nginx web server. From 2.0.0 until 2.5.0, ordinary authenticated users can access /api/nodes and /api/nodes/:id, whose responses serialize the node token field. The same token is accepted as X-Node-Secret by AuthRequired and maps the request to initUser, allowing the user to impersonate a trusted node against a reachable cluster member. This cross-node authentication bypass can expose sensitive management operations, including configuration synchronization and service restart. This issue is fixed in version 2.5.0.
