Allocation of Resources Without Limits or Throttling
Jetty is a java-based web server and servlet engine. In affected versions prior to 9.4.51, 10.0.x prior to 10.0.14,11.0.x prior to 11.0.14, and 12.0.x prior to 12.0.0.beta0 servlets with multipart support (e.g. annotated with `@MultipartConfig`) that call `HttpServletRequest.getParameter()` or `HttpServletRequest.getParts()` may cause `OutOfMemoryError` when the client sends a multipart request with a part that has a name but no filename and very large content. This happens even with the default settings of `fileSizeThreshold=0` which should stream the whole part content to disk. An attacker client may send a large multipart request and cause the server to throw `OutOfMemoryError`. However, the server may be able to recover after the `OutOfMemoryError` and continue its service `--` although it may take some time. Users are advised to upgrade. Users unable to upgrade may set the multipart parameter `maxRequestSize`, which must be set to a non-negative value, so the whole multipart content is limited (although still read into memory).
CWE-770 - Allocation of Resources Without Limits or Throttling
The software allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor.
