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 product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
