Description

This module leverages an authentication bypass in PaperCut NG. If necessary it updates Papercut configuration options, specifically the 'print-and-device.script.enabled' and 'print.script.sandboxed' options to allow for arbitrary code execution running in the builtin RhinoJS engine. This module logs at most 2 events in the application log of papercut. Each event is tied to modifcation of server settings.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
