Details

OutOfMemoryError for large multipart without filename in Eclipse Jetty ### Impact 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 a 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. A very large number of parts may cause the same problem. ### Patches Patched in Jetty versions * 9.4.51.v20230217 - via PR #9345 * 10.0.14 - via PR #9344 * 11.0.14 - via PR #9344 ### Workarounds Multipart parameter `maxRequestSize` must be set to a non-negative value, so the whole multipart content is limited (although still read into memory). Limiting multipart parameter `maxFileSize` won't be enough because an attacker can send a large number of parts that summed up will cause memory issues. ### References * https://github.com/eclipse/jetty.project/issues/9076 * https://github.com/jakartaee/servlet/blob/6.0.0/spec/src/main/asciidoc/servlet-spec-body.adoc#32-file-upload
