Apache Software Foundation · Apache Druid
Apache Druid, from the Apache Software Foundation, contains a flaw in its handling of user-provided JavaScript embedded in requests, where an authenticated user can craft a request that forces the server to run that JavaScript even when the feature is disabled in the server configuration. Exploitation requires only an authenticated user account, and successful exploitation allows arbitrary code execution on the target machine with the privileges of the Druid server process.
Apache Druid includes the ability to execute user-provided JavaScript code embedded in various types of requests. This functionality is intended for use in high-trust environments, and is disabled by default. However, in Druid 0.20.0 and earlier, it is possible for an authenticated user to send a specially-crafted request that forces Druid to run user-provided JavaScript code for that request, regardless of server configuration. This can be leveraged to execute code on the target machine with the privileges of the Druid server process.
First seen exploited 3 years after disclosure. Public exploit code (Metasploit) was available 8 days before disclosure.
