CVE-2018-17211-Unauthenticated Information Disclosure-PrinterOn

The PrinterOn web application, 4.1.4 and lower, is vulnerable to an Information Disclosure vulnerability due to the overly permissive read access on the "PrinterDetails" page. This behaviour is triggered by giving a valid "printerId", exposing the other existing printers.

Example of Default Printer IDs
  • 900005228231
  • 900784151735
  • 900739427876
