Summary

XStream is used in ITNCM to serialise data objects to XML and back again. XStream could allow a remote authenticated attacker to execute arbitrary commands on the system, caused by an unsafe deserialization flaw. By manipulating the processed input stream, an attacker could exploit this vulnerability to execute arbitrary commands on the system.
