Message | POLICY HP JetDirect LCD modification attempt |
Impact | User confusion and comedy, mostly.
|
Detailed Information | The HP JetDirect printers allow remote machines to change the message that is displayed on the LCD panel.
|
Affected Systems | |
Attack Scenarios | As part of an attempt to confuse and annoy users, an attacker may attempt to change the previously mentioned message. __ Ease of Attack: Relatively simple. All that is required is a way to connect to the JetDirect port of the victim printer and a minimal knowledge of how JedDirect works. A telnet/nc client would suit the job well, but there are also many featureful programs that'll allow you to accomplish the same ends.
|
Ease of Attack | |
Corrective Action | Update to the latest JetDirect, and investigate the possibility of restricting access to a central print-server using the "allow: <ip> <netmask>" directive in a printer config file.
