Cloud Native Computing Foundation Harbor before 1.10.3 and 2.x before 2.0.1 allows resource enumeration because unauthenticated API calls reveal (via the HTTP status code) whether a resource exists.

GHSA-q9x4-q76f-5h5j — Unauthenticated users can exploit an enumeration vulnerability in Harbor (CVE-2019-19030)

Affected: Go: github.com/goharbor/harbor

# Impact Sean Wright from Secureworks has discovered an enumeration vulnerability. An attacker can make use of the Harbor API to make unauthenticated calls to the Harbor instance. Based on the HTTP status code in the response, an attacker is then able to work out which resources exist, and which do not. This would likely be accomplished by either providing a wordlist or enumerating through a sequence an unauthenticated attacker is able to enumerate resources on the system. This provides them with information such as existing projects, repositories, etc.

The vulnerability was immediately fixed by the Harbor team.

# Issue The following API resources where found to be vulnerable to enumeration attacks: /api/chartrepo/{repo}/prov (POST) /api/chartrepo/{repo}/charts (GET, POST) /api/chartrepo/{repo}/charts/{name} (GET, DELETE) /api/chartrepo/{repo}/charts/{name}/{version} (GET, DELETE) /api/labels?name={name}&scope=p (GET) /api/repositories?project_id={id} (GET) /api/repositories/{repo_name}/ (GET, PUT, DELETE) /api/repositories/{repo_name}/tags (GET) /api/repositories/{repo_name}/tags/{tag}/manifest?version={version} (GET) /api/repositories/{repo_name/{tag}/labels (GET) /api/projects?project_name={name} (HEAD) /api/projects/{project_id}/summary (GET) /api/projects/{project_id}/logs (GET) /api/projects/{project_id} (GET, PUT, DELETE) /api/projects/{project_id}/metadatas (GET, POST) /api/projects/{project_id}/metadatas/{metadata_name} (GET, PUT)
