Synopsis

A web application running on the remote host is affected by a code execution vulnerability.

Description

According to its self-reported version number, the Puppet install running on the remote host is version 5.5.x prior to 2017.2.2. It is, therefore, affected by a denial of service vulnerability which exists in RBAC and classifier errors. An unauthenticated, attacker can exploit this, to use specially formatted strings w/ specific characters as classifier node group names or RBAC role display names to crash the service.
