The default configuration of the PJL Access value in the File System External Access settings on HP LaserJet MFP printers, Color LaserJet MFP printers, and LaserJet 4100, 4200, 4300, 5100, 8150, and 9000 printers enables PJL commands that use the device's filesystem, which allows remote attackers to read arbitrary files via a command inside a print job, as demonstrated by a directory traversal attack.

The remote host's PJL interface fails to sanitize input to the 'name' parameter of the 'fsdirlist' command before using it.

An attacker can leverage this issue using a directory traversal sequence to view arbitrary files on the affected host within the context of the PJL service. Information harvested may aid in launching further attacks.
