Description Guilherme de Almeida Suckevicz 2021-06-01 18:45:06 UTC
The vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Comment 1 Guilherme de Almeida Suckevicz 2021-06-01 18:45:31 UTC
Created xstream tracking bugs for this issue:

Affects: fedora-all [bug 1966736]

Comment 9 Jonathan Christison 2021-06-07 11:18:30 UTC
Marking Red Hat JBoss Fuse 6, Red Hat Fuse 7 and Red Hat Intergration Camel K as Moderate, although these products use vulnerable versions of XStream through the camel-xstream component https://access.redhat.com/documentation/en-us/red_hat_jboss_fuse/6.3/html/apache_camel_component_reference/idu-xstream Camel provides an extended default deny list with `org.apache.camel.xstream.permissions`, the default being `-,java.lang.,java.util.`, for this reason the attack complexity is significantly increased as this deny list is out of the attackers control.

Users overriding the org.apache.camel.xstream.permissions for unmarshalling of XML should ensure all classes are denied by default eg. `-*,com.misc.mypacakge.myclass`.
