Description
This security bulletin contains information about 1 security vulnerability.
1) Improper Authentication (CVE-ID: N/A)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to insecure configuration when installing Harbor with Harbor-helm. If the "core.secretName" option in the values.yaml is not set, the application will use the default and publicly available public/private key to sign the JWT token, which is used to push/pull images in Harbor. As a result, a remote non-authenticated attacker can forge the JWT token and push/pull images in Harbor without any authentication.
Remediation
Install update from vendor's website.
