DOS: HP JetDirect LCD Modification (TCP/9100)
This signature detects attempts to exploit a vulnerability in the printer control language used in HP JetDirect printers. Attackers can send maliciously crafted packets to TCP/9100 to print arbitrary messages on HP printers with LCD panels.
Extended Description
Certain versions of HP JetDirect enabled printers provide a function (PJL command) that changes the LCD display on a printer over TCP/IP. Arbitrary strings can be sent to the LCD display by a remote user using this command. This represents more of a nuisance than a threat, although it is conceivable that the ability to modify the display could be used in some sort of "social engineering" scheme.
