Is it exploited?

Yes. Previdian sensors observed exploitation attempts with confirmed confidence.

Who is affected?

amir20 / dozzle affected before 10.5.2.

What should we do?

Patch immediately, validate internet-facing exposure, and monitor for matching requests.

Overview

Dozzle is a realtime log viewer for docker containers

Dozzle is a realtime log viewer for docker containers. Prior to 10.5.2, in a default dozzle deploy (the documented quickstart, no DOZZLE_AUTH_PROVIDER set), POST /api/notifications/test-webhook is reachable without authentication and forwards an attacker-controlled URL into a WebhookDispatcher that sends an HTTP POST to the supplied URL with attacker-controlled request headers, and returns the response status code AND up to 1MB of the response body to the caller, when the target replies non-2xx.

This vulnerability is fixed in 10.5.2.
