Detailed vulnerability description

The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists due to improper parsing of user-supplied requests. A remote attacker can submit a specially crafted request, which when parsed by the YamlProvider feature of the affected application allows to execute arbitrary code with the permissions of the application using RESTEasy.

Successful exploitation of the vulnerability may result in full system compromise.
