Description

In WESEEK GROWI before 3.5.0, the site-wide basic authentication can be bypassed by adding a URL parameter access_token (this is the parameter used by the API). No valid token is required since it is not validated by the backend. The website can then be browsed as if no basic authentication is required.

Affected products

• WESEEK, Inc. GROWI: before 3.5.0 — fixed in 3.5.0

How to fix

Upgrade to a fixed version: WESEEK, Inc. GROWI 3.5.0. Check the vendor advisory for mitigations.
