Description
When Adobe ColdFusion’s Flex integration is enabled and configured to use Java RMI, a network service is exposed that allows arbitrary Java objects to be deserialized. By supplying a specially crafted object to this service an unauthenticated attacker could trigger the execution of arbitrary code on the server.
Remediation
Correct remediation of this vulnerability involves updating both Adobe ColdFusion and the Java runtime environment that it is configured to use. ColdFusion should be updated to a version greater than 11 update 12 or greater than 2016 update 4.
