Description
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.
Public exploits
Exploit or proof-of-concept code for this vulnerability is publicly available, which lowers the bar for attackers. Treat it as a reason to patch sooner.
Third-party code, not reviewed by us. Public PoCs are sometimes fake or contain malware. Read the code first and run it only in an isolated lab, against systems you are authorised to test.
