Vulnerability description
The vulnerability allows a remote attacker to execute arbitrary code on the server.
The weakness exists due to absent filtration in XStream instance when deserializing XML data within the REST Plugin. A remote attacker can upload a specially crafted XML file to vulnerable Apache Struts installation, trigger the XStreamHandler to process malicious XML payload and execute arbitrary core on the target system.
Successful exploitation of the vulnerability is possible in case the attacker is able to upload XML.
