Title: HP JetDirect LCD Display Modification Vulnerability
Severity: MODERATE
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.
