Harbor Multiple Vulnerabilities Threat Alert

Overview

Today, VMware released five vulnerabilities for Harbor Container Registry, including two officially classified as critical vulnerabilities (CVE-2019-19025, CVE-2019-19023), and two high-risk vulnerabilities (CVE-2019-19029, CVE- 2019-19026), and a medium-risk vulnerability (CVE-2019-3990).

Harbor is an open-source image management project that extends the open-source Docker Distribution by adding features usually required by users, such as security, identity, and management.

• CVE-2019-19025: Cross-Site Request Forgery (CSRF) vulnerability. The Harbor web interface does not implement a protection mechanism against CSRF. By attracting an authenticated user to a previously prepared third-party website, a third party can perform any operations on the platform in the context of the authenticated user or administrator.
• CVE-2019-19023: privilege escalation vulnerability. This vulnerability allows ordinary users to modify the email address of a specific user through API calls to gain privileges of the administrator account. The vulnerability stems from the fact that the Harbor API does not place appropriate permission restrictions on API requests that modify email addresses.
• CVE-2019-19029: SQL injection through user groups. Users with project management functions can read confidential information from the underlying database or elevate privileges via SQL injection.
• CVE-2019-19026: SQL injection through project quotas. A SQL injection vulnerability exists in the quotas section of the Harbor API. An authenticated administrator can send a specially crafted SQL payload via the GET parameter sort to extract sensitive information from the database.
• CVE-2019-3990: A user enumeration vulnerability. This vulnerability exists in the “/users” API endpoint. This endpoint should be restricted to administrators only. However, this restriction can be bypassed. Non-administrator users (such as those created via self-registration) can list all user names and user IDs and confirm the email address associated with a user name by sending a GET request to /api/users/search.
