Описание
XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker to load and execute arbitrary code from a remote host only by manipulating the processed input stream, if using the version out of the box with Java runtime version 14 to 8 or with JavaFX installed. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.
A flaw was found in xstream, a simple library used to serialize objects to XML and back again. This flaw allows a remote attacker to load and execute arbitrary code from a remote host by manipulating the processed input stream. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
Отчет
Users who follow the recommended security framework with a whitelist to limit the types to the minimum required should not be affected. XStream 1.4.18 no longer uses a blacklist by default since it cannot be secured for general purposes. OpenShift Container Platform (OCP) delivers the Jenkins LTS package with bundled XStream library. Due to JEP-200 [1] and JEP-228 [2] Jenkins projects, the OCP Jenkins package is not affected by this flaw. This version of the XStream library will be delivered in future Jenkins releases.
