Summary
Apache Axis2/Java reads multipart and form-encoded request bodies without any size limit and does not delete the temporary files it creates. An unauthenticated caller can send oversized requests to exhaust the server's memory or disk.

Read the original description
Allocation of Resources Without Limits or Throttling vulnerability in Apache Axis2/Java. The multipart/form-data and application/x-www-form-urlencoded message builders read the request body directly from the transport stream with no size limit, so the servlet container's post-size limit did not apply, and multipart temporary files were not deleted. An unauthenticated caller could exhaust memory or disk. Version 2.0.2 bounds these bodies with configurable limits and deletes temporary files. This issue affects Apache Axis2/Java: through 2.0.1. Users are recommended to upgrade to version 2.0.2, which fixes the issue.
