Cloud credential disclosure via incomplete HTTP denylist
Published Jul 7, 2023 · Updated Nov 19, 2024
Server-side request forgery in CC: Tweaked allows remote authenticated users to read cloud metadata through its HTTP API. The PrivatePattern address predicate omits several metadata-service addresses from the default deny rules, so player-supplied Lua HTTP requests reach Alibaba Cloud, Oracle Cloud, or AWS metadata endpoints. Exposure requires a cloud-hosted Minecraft server with the HTTP API enabled and a configuration that is not whitelist-only; disclosed data can include boot secrets or cloud credentials.
