| Descrição | The UEditor "catch image" feature fetches each URL supplied in a request parameter server-side and passes the bytes into the upload pipeline. A URL-validation routine restricts the scheme to http/https and rejects hosts that resolve to internal IP addresses, but the check is performed against the host string in isolation and is bypassable via DNS rebinding and the time-of-check / time-of-use gap between validation and the subsequent download. On deployments where the web-facing editor route is enabled (ms.basic.upload.enableWeb), the endpoint is reachable without authentication, so a remote attacker can make the MCMS server issue HTTP requests to attacker-chosen destinations, including internal services once the IP check is bypassed. |
