Detailsinfo

A vulnerability was found in Appsmith up to 2.0 and classified as critical. This issue affects some unknown processing of the file docker-compose.yml. The manipulation with an unknown input leads to a routine vulnerability. Using CWE to declare the problem leads to CWE-749. The product provides an Applications Programming Interface (API) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Appsmith is a platform to build admin panels, internal tools, and dashboards. Prior to 2.1, the bundled Caddy reverse-proxy's admin API — which has no authentication by default — is bound on 0.0.0.0:2019 inside the container. While this listener is not directly published to the host by docker-compose.yml, it is reachable from the Appsmith server process itself or a SSRF vulnerability. An authenticated low-privileged user can therefore drive the SSRF to issue POST /load (or any other admin-API call) against http://0.0.0.0:2019/, fully replacing the live Caddy configuration and taking over the reverse proxy. This vulnerability is fixed in 2.1.
