Readme or Release notes:

A vulnerability in the Jakarta multipart parser of Apache Struts could allow an unauthenticated, remote attacker to execute arbitrary code on an affected system.
The vulnerability is due to improper handling of the Content-Type header value when performing a file upload based on the Jakarta multipart parser of the affected software. An attacker could exploit this vulnerability by persuading a targeted user to upload a malicious file. Once the Jakarta multipart parser of the affected application uploads the file, the attacker could have the ability to execute arbitrary code.
