Software running under User Account: PONservice (part of local administrators group)

Software Notes
Per the PrinterOn Enterprise 4.1.4 Installation Guide on Page 10, a local administrator account is required to run the software.

On a default installation, the Post Print Option is to aDelete From Storea. Meaning, if you upload a file to print, this file is deleted immediately after it is printed.

When printing as a Guest or Authenticated user, you have the choice of either uploading a file to be printed or entering a Web Page. The file type you upload or supply via URI needs to be supported by the application in order for it to process and print. Per page 11 of the installation guide, under Recommended Software, itas advised to install an application such as Microsoft Word to print .docx documents. There is also some additional configuration needed to be able to print specific file types otherwise you receive an error such as aThis type of file cannot be processed by your servicea.

When either printing as a Guest (when enabled) or as an Authenticated user via the CPS URL https://<hostname or ip>/cps, the user printing has the ability to delete any file on the host system that isnat currently in use by the system itself. The field to enter a web page does not properly check the URI being entered, as such the user can enter a system file path and delete a file on the system.

Login as either Guest or an Authenticated user to print
https://<hostname or ip>/cps
Choose any printer
Entering a system path to a file in the web page field
C:\Program Files (x86)\PrinterOn Corporation\Apache Tomcat\Conf\web.xml
Send the print job, an error will show
Check system, file is deleted

By deleting specific files the application, and possibly the host system, can become unusable.
