Cloud Native Computing Foundation Harbor prior to 1.8.6 and 1.9.3 has a Privilege Escalation Vulnerability in the VMware Harbor Container Registry for the Pivotal Platform.

Harbor API has a Broken Access Control vulnerability. The vulnerability allows project administrators to use the Harbor API to create a robot account with unauthorized push and/or pull access permissions to a project they don't have access or control for. The Harbor API did not enforce the proper project permissions and project scope on the API request to create a new robot account.

A User Enumeration flaw exists in Harbor. The issue is present in the "/users" API endpoint. This endpoint is supposed to be restricted to administrators. This restriction is able to be bypassed and information can be obtained about registered users can be obtained via the "search" functionality.

Impact

Hidde Smit from Cyber Eagle has discovered an User Enumeration flaw in Harbor. The issue is present in the "/users" api endpoint. This endpoint is supposed to be restricted to administrators. This restriction is able to be bypassed and information can be obtained via the "search" functionality.

Non-administrator users (such as those created via self-registration) can list all usernames and user IDs by sending a GET request to /api/users/search with parameter "username" and value "", as follows:

curl -X GET "https://<host>/api/users/search?username=" -H "accept: application/json" --user <user>:<password>

The vulnerability was immediately fixed by the Harbor team and all supported versions were patched. With the patched versions of Harbor, the username is required for search and we have removed the support for querying by email.

Patches If your product uses the affected releases of Harbor, update to either version 2.1.0 or 2.0.3 to fix this issue immediately
