Description

A vulnerability in Pelican Panel’s /api/remote/* endpoints allows any valid node token (remote.token_id + remote.token) to access server data for servers hosted on other nodes. This effectively turns any node token into a global API key for all nodes.

Each Wings node in Pelican has unique tokens defined in wings/config.yml. These credentials should only allow access to servers physically assigned to that node.

However, during testing, I found that:

  • Node-1’s token could be used to query and retrieve details for a server assigned to Node-2.
  • The request was made to the Panel’s /api/remote/servers/{uuid} endpoint, not directly to Wings.
  • The Panel accepted the token without verifying that it matched the server’s assigned node.

This means token scope validation is missing or incorrect in the Panel’s remote API.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
